PEI refers to polyetherimide, which is an amber transparent solid. It has inherent flame retardancy and low smoke without adding any additives. The oxygen index is 47%, the combustion level is UL94-V-0, and the density is 1.28. ~1.42g/cm3. PEI has strong high temperature stability, even non-reinforced PEI still has good toughness and strength. The long-term…

PEEK is a high temperature resistant, high performance thermoplastic special engineering plastic. It has good mechanical properties, chemical resistance, abrasion resistance, hydrolysis resistance, etc.; it has light specific gravity and good self-lubricating performance. Due to its very good processing performance, it can be filled with carbon fiber, molybdenum disulfide, etc. to further improve the lubricating…

Acrylic has good weather resistance and strong hardness, and can be made into various required products, but acrylic is also good or bad, which is directly related to its service life, so what kind of acrylic material to choose becomes a headache for people. So, what are the performance characteristics and uses of acrylic material?…

1. ABS plastic is a terpolymer of acrylonitrile (A)-butadiene (B)-styrene (S). It combines the properties of three components, among which acrylonitrile has high hardness and strength, heat resistance and corrosion resistance; butadiene has impact resistance and toughness; styrene has high surface gloss, easy coloring and Ease of processing. 2. The structure of ABS resin includes…

Classification, characteristics and applications of polypropylene (PP) plastics Poly(propylene) (1) Polypropylene (PP) production process Polypropylene is made by addition polymerization of propylene, CH2=CHCH3, under the action of Z-N metal catalyst. (2) Production method of polypropylene (PP) ① Slurry method. Polymerization in a diluent (such as hexane) is the earliest industrialized method and the largest production…

Nylon is a kind of engineering plastic with excellent performance. It has excellent mechanical properties, outstanding corrosion resistance, oil resistance, heat resistance, high modulus and other advantages. Reinforcement and flame-retardant modification can significantly improve its heat resistance, modulus dimensional stability and flame retardancy, and are widely used in industries such as automobiles, electronic and electrical,…

The characteristics of pc material bai are: 1. Amorphous material, good thermal stability, wide molding temperature range and poor fluidity. zhi absorbs little moisture, but is sensitive to water, so it must be dried. Molding shrinkage is small, melting cracking and stress concentration are easy to occur, so molding conditions should be strictly controlled, and…
