Guide for Injection Molding Materials

We have over 200 line items of Injection Materials in-house and we can run customer supplied materials along with sourcing specific materials or colorant that are not readily available. Below is a guide to some of our “General Purpose” plastic resin materials and their datasheets that we carry in stock.

*This is for reference only. We recommend contacting us directly or the resin manufacturer to assist in which material is best suited for your application.

ABS | Acrylonitrile Butadiene Styrene
PORENE AN450
Known for being impact resistance and its toughness. Our ABS Porene AN450 is a flame retardant grade ABS. Generally ABS has useful characteristics within a temperature range from -40° to 212 °F.

Some uses include: Automotive body parts, wheel covers, enclosures, etc.
ACETAL 500P
DELRIN 500P
Very strong and exhibits good chemical resistance. Acetal is a tough material with good dimensional stability, naturally lubricating and remain stable at high temperatures. Delrin 500P has a higher tensile strength compared to 100P. This makes it stiffer and has better impact strength.

Some uses include: Gears, springs, plates, bushings, housings, etc.
ACETAL 100P
DELRIN 100P
Very strong and exhibits good chemical resistance. Acetal is a tough material with good dimensional stability, and naturally lubricating. Some uses include: Gears, springs, plates, bushings, housings, etc.
NYLON 6/6
ZYTEL 101L
A versatile engineering thermoplastic. It is strong, rigid, and has a very high melting point. Because of its excellent balance of strength, ductility and heat resistance, nylon 6/6 is an outstanding candidate for metal replacement applications. It is impact and abrasion resistant, and also self-lubricating. Some weaknesses of nylon is that it has high water absorption and poor chemical resistance to strong acids and bases.

Some uses include: Bearings, bushings, valves, seats, rollers, wear surfaces, etc.
NYLON GF | 13% & 33%
ZYTEL 70G33L
Has outstanding wear and abrasion resistance, excellent impact resistance, chemical and heat resistance, low friction and self lubricating. 33% Glass Filled has 200% better strength than general purpose nylon. It also cuts down on warping due to water absorption.

Some uses include: Office chairs, outdoor power equipment, outboard motor covers, and gun stock components
PEI | Polyetherimide
ULTEM
Offers outstanding creep behavior, excellent chemical resistance, exceptionally low smoke generation, and inherent flame retardancy. It exhibits superior strength, modulus, thermal, electrical, and mechanical performance. FDA and food compliant.

Some uses include: Medical devices, aerospace components, chemical testing.
PC/ABS
BAYBLEND T85
Is a blended material of ABS with Polycarbonate which offers a good combination of mechanical and thermal properties. This material offers good impact strength, even in cold temperatures, rigidity, dimensionality, thermal and color stability. A limitation is poor chemical resistance.

Some uses include: Door handles, electronics housing, computers, printers, etc.
PC | Polycarbonate MAKROLON 2458
LEXAN 940A
Transparent amorphous polymer which exhibits outstanding physical properties such as impact resistance (almost unbreakable), heat resistance up to 125°C and excellent clarity. Polycarbonate is often used to replace glass or metal in demanding applications when the temperature does not exceed 125°C. Some uses include: Power tools, small appliances, Blu-ray discs, safety glasses, toys, etc.
PLA |
Polylactic Acid
A bioplastic that is used in place of plastics such as Polystyrene, ABS, etc. It is compostable, and made from corn. Many different grades are available.

Some uses include: cutlery, phone cases, packaging, agriculture, house hold goods, etc.
POLYPROPYPLENE
HOPP 20
A tough material with flexibility, which is good for hinged parts. Good tensile strength and inertness toward acids, alkalis and solvents. PP has very low density and light weight.

Some uses include: Packaging, parts for electronic and electrical appliances, food containers, hinged parts, toys, household goods, etc.
PVC | Polyvinyl Chloride
GEON M5200
Durable, long lasting material that comes in rigid or flexible states. GEON M5200 is a rigid PVC. PVC has inherent flame retardent, and chemical resistant.

Some uses include: Windows, piping, wire insulation, automotive interiors.
TPE/TPV/TPU | Thermoplastic Elastomers
Versaflex, Santoprene
Have similar properties and feel to natural rubber, but have a longer life. TPE's are good in both hot and cold environments, it is often preferred over rubber. They have good tear strength and often used for overmolding and living hinges. TPV's such as Santoprene chemically bond to certain rigid materials that can improve product longevity.

Some uses include: consumer goods to medical instruments to industrial tools and can include knobs, handles, gaskets, seals and grips, etc.
