Polyethylene Terephthalate for High-Performance Parts

Rynite® unites the best properties of reinforced polyethylene terephthalate (PET) with easier processability to produce high-performance parts.

With its lightweight, glass-reinforced composition, dimensional stability, durability, and high-gloss finish, DuPont™ Rynite® is preferred across a wide range of applications, particularly as a replacement of die-cast metals and thermosets.

This stiff, UV-resistant polymer offers a balance of thermal, mechanical, and chemical properties that make it ideal for electrical and electronic parts. Rynite® offers superior flow characteristics as well, which means it fills complex, thin-walled moulds with less injection pressure than is needed with other resins - a big advantage in the miniaturization of parts.

Rynite® polyethylene terephthalate (PET) helps make electrical devices, photovoltaic panels, switches, and other critical energy components stronger and reliable.

DuPont™ Zytel® is a portfolio of nylon resin materials proven in a wide range of applications. Zytel® products deliver high-performance benefits ranging from stiffness to heat resistance.

Manufacturers of everything from automobiles to consumer electronics rely on DuPont™ Zytel® whenever they have an application demanding high-performance nylon. Zytel® PA has been an industry leader for more than 70 years, and continues to be preferred for a broad array of new materials and technical collaborations worldwide.

DuPont™ Hytrel® TPC-ET thermoplastic elastomer combines the flexibility of rubber with the strength and processability of thermoplastics. Manufacturers prefer parts made with Hytrel® for their resilience, heat and chemical resistance, as well as their strength and durability.

Hytrel® drives innovative design, enabling the development of unique parts with multiple performance characteristics. This versatile thermoplastic elastomer resin can flex in multiple directions, cycle after cycle, long after rubber would break. Its durability has made it an essential ingredient in automotive components such as the Constant Velocity Joint (CVJ) boot, which must endure an average of 150,000 miles of pounding over a wide range of temperatures.

DuPont™ Hytrel® RS delivers all of the benefits of Hytrel®, yet it contains up to 60 percent renewably sourced materials from non-food biomass, making it an excellent product for applications demanding renewably sourced options.

Minlon® nylon resin include mechanical and physical properties such as high mechanical strength, excellent balance of stiffness /toughness, good high temperature performance, good chemical resistance, paintability, dimensional stability and low warpage.

Grades with improved electrical and flammability properties are available within the Zytel® nylon resin product line. In addition, Minlon® nylon resin is available in different modified and reinforced grades to create a wide range of products with tailored properties for specific processes and end-uses.

The good melt stability of Minlon® nylon resin normally enables the recycling of properly handled production waste. If recycling is not possible, DuPont recommends, as the preferred option, incineration with energy recovery (-31kJ/g of base polymer) in appropriately equipped installations. For disposal, local regulations have to be observed.

Minlon® nylon resin typically is used in demanding applications in the automotive, electrical, electronic, domestic appliances and construction industries.

A family of cost-effective, high-performance polyamides

For manufacturers across a number of industries, Zytel® HTN high-performance polyamide resin is the choice for reducing weight, improving strength, enhancing durability, increasing thermal performance, and simplifying processing.

The Zytel® family of products is available in a variety of grades that sustain high strength and stiffness over a wide range of temperatures, chemicals, and moisture exposure.

Zytel® HTN is widely used to replace metal parts that must withstand high temperature tolerances (such as engine cooling, handheld devices, and non-halogenated connectors), while reducing cost and weight.

In both PPA grades and structural grades, Zytel® HTN solutions enhance performance in a diverse array of applications

Delrin® acetal homopolymer (Polyoxymethylene POM) is the ideal material in parts designed to replace metal. It combines low-friction and high-wear resistance with the high strength and stiffness such applications require. It provides a wide operating temperature range (-40 °C to 120 °C) and good colourability. Delrin® also mates well with metals and other polymers and offers excellent dimensional stability in high precision moulding.

Delrin is a Homopolymer acetal(POM-H) and its a DuPont Trade name for it. Delrin Offers high tensile strength, stiffness, creep resistance and has excellent flex fatigue resistance when compared to other acetal co-polymers. It has excellent dimensional stability. We offer rods manufactured from Food grade Delrin material also.
