Plastic Materials Selection
For a general guide to choosing resins for injection molding parts.
Selecting the correct material for each application can be a daunting task, requiring in-depth knowledge Recommending the right type and grade of resin hinges on a thorough understanding of the product’s application; all application characteristics need to be carefully weighed before a determination is made of the panoply of injection molding resins available. And we are happy to work with specific resins you already use and would like to supply to us.
Partial Thermoplastics and Thermoset Raw Materials Overview:
IMPORTANT: Information below is a general plastic materials description overview, and is intended for preliminary material identification ONLY.
The amorphous polymer that’s easy to work. Good impact strength and appearance. Poor chemical resistance. Commonly used in computer shells, medical parts, hand-held appliances, auto trim parts. Flame retardant and medical grade availability.
Applications: Computer housings, small appliances, automotive various small parts, and medical components
Stronger than ABS. Exceptional impact strength at low temperatures. Flame retardant grades available. Less expensive than Polycarbonate. Limited availability due to the worldwide shortage.Applications: Automotive interior and exterior components, medical hardware, electrical housings, computers, monitors, business equipment housings and enclosures
Acetal Polymers that are semi-crystalline and have excellent fatigue resistance, lubricity, and chemical resistance. It can omit gasses at higher temperatures. Brittle at lower temperatures. Enhanced lubrication and glass-filled grades available.
Applications: Mechanical Automotive, Business Machine, and Household Appliance, Components i.e. Slides, Gears, Cams, Bushings, Door Handles, and Seat Belt Parts.
Amorphous polymers offering superb clarity. Used in optical applications. Excellent weather durability for outdoor applications.
Applications: Automotive, Transparent Items such as Head/Tail Lenses and Trim, Household Light Fixtures and Decorative Items, Safety Equipment, and Shields.
Semi-crystalline polymer with low cost and high-performance versatility and the lowest modulus of all nylon. Lower grades subject to property change if exposed to moisture. It can be reinforced with compounds and additives to expand the property range.
Applications: Automotive components, Bearings, Electronic Connectors, Gears, Consumer ProductsandIndustrial products
Improved properties over Nylon 6. h3 abrasion resistance. Glass fiber reinforcement grades used for metal replacement.
Applications: Automotive components, electronic connectors, gears, consumer products, and industrial products.
Less susceptible to moisture absorption than Nylon 6 and 6-6. Compounded with reinforcements and additives to increase property stability and range including impact strength, flexibility, and dimensional stability.
Applications: Automotive components, Electronic connectors, Gears, Consumer products, and Industrial products.
Versatile, semi-crystalline materials with broad property range. Performance is similar to Nylon. Resists abrasion, temperature, moisture. Effective electrical barrier with superb impact strength. Subject to failure is notched under stress. Difficult to mold to extremely tight tolerances.
Applications: Industrial equipment applications, business equipment, automotive housings-under the hood, power tool casings
LCP (Polyester Liquid Crystal Polymer)
plastic Material made of polymer molecules with Tensile Strength and modulus close to aluminum. Molecular orientation causes structural strength to be only inherent in the outermost skin layers, presenting design, and molding challenges.
Applications: Electrical and Mechanical parts, Food containers, and any other applications requiring chemical inertness and high strength.
Semi-crystalline material. Wide range of properties, usage, and cost. Chemical and low- temperature resistant. Difficult to mold to very close tolerances.
Applications: Packaging, industrial components for fluid processing, household goods, automotive and electrical hardware.
Amorphous material with superb clarity, Impact Strength, and mechanical properties. Widely used in optical applications. Medium weather durability. Limited availability.
Applications: Automotive Headlights, Business Machines, Consumer Products, Telecommunications, Medical Products, and Mechanical Goods.
Available in both amorphous and crystalline grades. Excellent at high temperatures. Susceptible to all. Expensive.
Applications: Automotive Headlights, Business Machines, Consumer Products, Telecommunications, Medical Products, and Mechanical Goods
PO Modified Polyphenylene Oxide
(Noryl) Amorphous material with properties superior to ABS, although more expensive. Good Impact Strength, stiffness, surface appearance. Chemical resistant. Flame retardant.
Semi-crystalline material. Available in a wide range of compounded variations, providing good mechanical properties. Excellent resistance to chemicals and high temperatures. Popular and effective bearing material.
Applications: Hydraulic components, bearings, cams, valves, and electronic parts
An amorphous, temperature-resistant, transparent material with reasonably low cost. Effective at up to 300 F. Can be compounded with glass and minerals.
Applications: Appliance parts, electronic parts, automotive parts, medical components, business Equipment, aerospace and insulators.
LSR Liquid Silicone Rubber
Inorganic synthetic elastomer made from a cross-linked silicon-based polymer reinforced with filler. It provides long service life retaining natural flexibility and resilience. Weather-resistant, temperature resistant, good electrical insulating qualities, excellent sealing performance, Inert (no taste or smell), range of colors and hardness, excellent flow properties for fabrication.
Applications: Gaskets, Seals, Bushings, Connectors, Electrical parts
Most materials are available in many colors
Clear – available in ABS, polycarbonate, styrene, and acrylic.
