DuPont: A Top Plastic Manufacturer
Chemical Resistant Materials
DuPont is a leading plastic manufacturer known for strong chemical resistance. The company offers three main materials: Delrin, Vespel, and Teflon (PTFE). Each material has special benefits for tough environments.
Delrin resists solvents, oils, and fuels very well. It also handles hydrolysis better than general acetal. Vespel fights chemical corrosion with great strength. The Vespel SCP-5000 grade gives better toughness, thermal stability, and chemical resistance. It beats Vespel SP-1 in plasma resistance, dimensional stability, and chemical resistance. Vespel SP-1 balls and rod and sheet forms offer a wide mix of temperature resistance, chemical resistance, mechanical toughness, natural lubricity, wear resistance, and insulation properties.
Material | Chemical Resistance Properties |
|---|---|
Delrin® | Excellent resistance to solvents, oils, and fuels; better hydrolysis resistance than general acetal |
Vespel | Highly resistant to chemical corrosion |
DuPont shows up often on high-temperature plastics and high-performance plastics leader lists. It supplies polyimides, PPA, PEEK blends, and engineering resins for automotive, aerospace, and electronics. Its long history in advanced polymers and composites makes it a key supplier for OEM polymer-substitution programs.
Applications and Industries
DuPont's chemical resistant materials serve many industries. In chemical processing, you can use Tyvek 800, Tychem 10000, and Tychem 2000 Tape for insulation work and line breaking. Tychem 2000 works for preventative maintenance and laboratory tasks. Tychem 10000 handles emergency response. For loading and unloading rail cars or trucks, Tyvek 400, Tychem 4000, and Tychem 2000 SFR are good choices.
Vespel polyimide parts and shapes help aerospace, semiconductor, chemical, and industrial uses. These components give thermal stability, low friction, wear resistance, and dimensional control in harsh conditions. They work as bushings, seals, wafer guides, bearings, and parts exposed to heat and tough environments. This helps replace heavier materials while making parts last longer and work better in extreme conditions. Other uses include flexible printed circuit boards, aerospace wire and cable insulation, semiconductor manufacturing, automotive sensors and electronics, and medical devices like catheters and endoscopes.
Ensinger Chemical Resistant Plastics
Ensinger makes strong plastic for tough chemical jobs. The company sells three main product groups: TECAPEEK, TECATRON, and TECAFLON. Each group targets different chemical needs.
Key Materials
TECAPEEK is made from PEEK and works well for parts that face heat or solvents, staying stable at high temperatures and staying strong. TECATRON uses PPS to blend heat and chemical resistance with strength, so you often use it for support parts. TECAFLON uses PVDF to give great chemical inertness and low friction, making it good for parts that touch strong process chemicals.
The table below shows the chemical resistance ratings for these product lines.
Polymer (Product Line) | pH Range | Weak Acids | Strong Acids | Weak Alkalis | Strong Alkalis | Alcohols | Cold Water | Hot Water |
|---|---|---|---|---|---|---|---|---|
PEEK (TECAPEEK) | 0.5–13.5 | + | (+) | + | + | + | + | + |
PPS (TECATRON) | 0.5–13.5 | + | + | + | + | + | + | + |
PVDF (TECAFLON) | 0.5–13.5 | — | — | — | — | — | — | — |
Please note: PVDF reacts strongly to hot alkalis. Do not use it above pH 12 and 40°C. Glass fiber types have a bit less resistance to strong alkalis. In the table, + means it resists, (+) means limited, and - means no resistance.
Chemical Exposure Scenarios
You can find Ensinger materials in semiconductor making. They handle wet processes, chemical mechanical polishing, plasma etching, and chemical delivery parts. For example, TECAPEEK works well with hydrofluoric acid and hydrogen peroxide. TECATRON resists sulfuric acid and nitric acid. PTFE handles acetone and ethanol without problems.
The drug industry also uses Ensinger plastics. In one study, Tecapeek Natural (PEEK) went through nitrogen dioxide sterilization. Tests included FTIR-ATR, EPR, DSC, and tensile testing. The material showed no cell harm. Tecapro MT (polypropylene) also passed similar tests. For chromatography systems, TECADUR MT TR natural copolyester stayed clear after 45 kGy gamma radiation. It did not change color like polycarbonate. It showed no material change per the BPOG Standard Extractable Protocol.
For chemical processing, pick materials for your specific chemicals. TECAPEEK works with deionized water, 2-propanol, and ethanol. TECATRON handles hydrochloric acid and ammonia solution. TECAFLON resists strong acids like sulfuric acid and hydrofluoric acid.

Comparing Materials and Choosing a Supplier
Material Resistance Overview
You face a wide range of chemical resistant plastics. Each one performs differently against acids, bases, and solvents. PTFE stands out as the best choice for pure chemical resistance. It handles strong oxidizers and nearly all corrosive substances. PP works well for less aggressive environments at a lower cost. PEEK delivers excellent resistance plus high-temperature stability. PVDF offers great chemical inertness but reacts strongly to hot alkalis. HDPE resists many acids and bases at moderate temperatures. PPS blends chemical resistance with mechanical strength.
The table below compares PTFE and PP for chemical handling applications.
Criterion | PTFE | PP |
|---|---|---|
Corrosion resistance | Exceptional; withstands a wide range of corrosive substances, ideal for strong acids and bases | Good but less versatile; may degrade with certain solvents or high temperatures |
Durability & longevity | Outperforms PP in most corrosive environments; maintains structural integrity under extreme conditions | More cost-effective for less aggressive environments where extreme durability is not critical |
Cost | More expensive due to superior properties and manufacturing processes | More economical, practical when budget constraints are significant and highest chemical resistance is not required |
Best-fit application | Maximum corrosion resistance and durability (e.g., chemical processing, pharmaceuticals) | Less demanding environments where a more economical solution suffices |
Selection Factors
Temperature plays a major role in material selection. All chemical and physical processes that affect resistance speed up as temperature rises. A material that resists a chemical at room temperature may fail at an elevated operating temperature. Chemical concentration matters too. Resistance generally decreases as the concentration of the medium increases and as exposure time grows.
Mechanical requirements also shape your choice. Chemical attack can degrade tensile strength and impact resistance through molecular chain degradation. Swelling from weaker solvents softens plastics and changes their flexibility. Stress cracking from chemicals can lead to brittle fracture. You must determine if tensile strength, flexural strength, and impact strength are critical for your part.
Cost often decides between two suitable materials. PTFE costs more than PP. You pay for superior chemical resistance and durability. PP saves money when your environment is less demanding.
International standards give you a consistent way to test chemical resistance. ASTM D543 covers rigid plastics and broad chemical screening. ISO 175 serves international specifications with a focus on flexural property retention. ASTM D471 tests rubber and elastomers for volume swell and hardness change. ASTM D1693 screens polyethylene for environmental stress cracking.
Always consult manufacturer data sheets before you finalize your order.
In marginal cases, the manufacturer's technical datasheet and testing under real conditions should be relied upon.
A reliable plastic manufacturer will provide these documents and connect you with their technical support team. Ask about your specific chemicals, temperatures, and mechanical loads. This step prevents costly failures in the field.
DuPont, Ensinger, Selon, Röchling, and other suppliers are among the top plastic makers for chemical resistant materials. Each one brings different strengths to your project. DuPont offers Teflon and Vespel. Ensinger provides TECAPEEK and TECATRON. Selon delivers Polysylene Thermoplastic Elastomer for seals and tubing.
Your best choice depends on the specific chemicals you handle, your operating temperatures, and your mechanical requirements. PTFE resists virtually all chemicals. PEEK handles most acids and bases up to 170°C. PPS outperforms other materials in strong sulfuric acid.
Always check manufacturer data sheets and talk to technical support teams before you finalize a material. This step prevents costly failures and ensures your parts work reliably in harsh environments.
