Unfilled polypropylene has rather low impact and stiffness. As a result, polypropylene materials are often modified to improve their mechanical properties. To improve stiffness the polypropylene can be compounded with short glass fiber (SGF-PP) or long glass fiber (LGF-PP). Key benefits of glass reinforced polypropylene compounds include significant increase in tensile, flexural, and heat performance. […]

Plastics Profiler-Nylon 66
Nylon 66 is a crystalline engineering thermoplastic made up of hexamethylenediamine and adipic acid that undergo a condensation reaction to form the polymer and is noted for the following performance characteristics: Chemical Resistance Abrasion Reistance Friction Resistance Heat Resistance Nylon 66 is commonly available in general purpose, glass reinforced and impact modified grades. For 33% […]
Plastics Profiler-Polycarbonate
Polycarbonate resins are amorphous thermoplastic polymers based on bisphenol A. Polycarbonate is noted for the following performance characteristics: High Impact Strength Dimensional Stability Heat Resistance Memory Clarity A major drawback of polycarbonate is its susceptibility to chemical attack in certain end use environments. Avoid using PC in environments with methyl alcohol, acetone, ketones, ethers, aromatic […]
Plastics Profiler-Acetal
Acetal resins are semi-crystalline, thermoplastic polymers commonly referred to as polyoxymethylene (POM). Acetal is noted for the following characteristics: Mechanical Strength Rigidity Natural Lubricity Chemical Resistance Fatigue Endurance Acetal is made by the polymerization of formaldehyde. When overheated acetal can form gaseous decomposition products that are largely formaldehyde and can cause irritation to the skin, […]
