Plastic Molding Material selection can significantly affect your plastic part’s tensile strength, temperature resistance, appearance, duration, and production cost. Our huge and always current knowledge of commodity through high-temperature thermoplastic as well as thermoset materials – including resins and liquid silicone rubber (LSR) – will prove important for expediting the plastic molded part material selection process.
Amorphous polymer that’s simple to work with. Good impact strength and look. Deprived chemical resistance. Commonly used: computer shells, hand-held appliances, medical parts, auto trim parts. Flame retardant & medical grade available.
Stronger than ABS. Outstanding impact strength at low temperatures. Flame retardant grades available. Less expensive than Polycarbonate. Limited availability because of worldwide shortage.
Acetal Polymers that are semi-crystalline and have tremendous fatigue resistance, lubricity, and chemical resistance. Can leave out gasses at higher temperatures. Brittle at lower temperatures. Improved lubrication & glass-filled grades available.
Amorphous polymers offering excellent clarity. Used in optical applications. Excellent weather sturdiness for outdoor applications.
Semi-crystalline polymer with low-cost with high performance versatility as well as the lowest modulus of all nylon. Lower grades subject to property modify if exposed to moisture. Can be reinforced with compounds and additives to increase the range of property.
Enhanced properties over Nylon 6. Resistance to abrasion H3. Glass fiber reinforcement grades intended for metal replacement.
Less vulnerable to moisture absorption that Nylon 6 & 6-6. Compounded with strengthening’s and additives to enhance property stability and range as well as impact strength flexibility and dimensional stability.
Versatile, semi-crystalline materials with wide property range. Performance like Nylon, Resists abrasion, temperature, moisture. Effective electrical barrier with outstanding impact strength. Subject to failure if jagged under stress. Difficult to mold to very tight tolerances.
Material made of polymer molecules with tensile strength as well as modulus close to aluminum. Molecular orientation causes structural strength to be only intrinsic in the outermost skin layers, presenting design & molding challenges.
Semi-crystalline material. Broad variety of properties, usage, and cost. Chemical and low-temperature resistant. Hard to mold to very close tolerances.
Amorphous material with excellent clarity, impact power, and mechanical properties. Extensively used in optical applications. Medium weather toughness. Limited availability.
Obtainable in both amorphous & crystalline grades, Excellent at high temperatures, Susceptible to alkali, And Expensive.
Amorphous material with properties better to ABS, although more luxurious. Excellent impact strength, rigidity, surface appearance, Chemical resistant, Flame retardant.
Semi-crystalline material. Available in a broad range of compounded variations, providing good mechanical properties. Excellent resistance to chemicals as well as high temperature. Popular and effectual bearing material.
Amorphous, temperature-resistant, transparent material with sensibly inexpensive. Effective at up 300ᵒF can be compounded with glass & minerals.
Choosing the wrong material can lead to early component failure as well as consequences ranging from inconvenient to very costly.
