Covestro PC 2805

PC material is actually one of the engineering plastics we refer to. As a widely used material worldwide, PC has its own characteristics and advantages and disadvantages. PC is an amorphous thermoplastic resin with excellent comprehensive performance, including excellent electrical insulation, elongation, dimensional stability, chemical corrosion resistance, high strength, heat resistance, and cold resistance; It also has the advantages of self extinguishing, flame retardant, non-toxic, and colorable. You can see the shadow of PC plastic in every corner of your life. The characteristics of large-scale industrial production and easy processing also make its price extremely low.

Performance characteristics of PC:

1. Good transparency, with a light transmittance of 90%, making it a transparent material with better heat resistance than PMMA (140 ° C);

2. Good low temperature resistance, can be used for a long time at -100 ° C-140 ° C;

3. Outstanding impact resistance, creep resistance, and dimensional stability; Outstanding impact resistance, creep resistance, and dimensional stability;

4. Good electrical insulation at a wide temperature range (-100-140 ° C) and a wide frequency range (60-10106Hz); Good electrical insulation at a wide temperature range (100~℃) and a wide frequency range (Hz); Good electrical insulation;

5. Good processability (injection, extrusion, blowing, salivation, compression, etc.).

Physical properties of PC: Density: 1.20-1.22 g/cm ^ 3 Linear expansion rate: 3.8 × 10 cm/cm ° C Heat deformation temperature: 135 ° C Low temperature -45 ° C Polycarbonate is colorless and transparent, heat-resistant, impact resistant, flame-retardant BI grade, and has good mechanical properties at normal operating temperatures. Compared to polymethyl methacrylate, polycarbonate has better impact resistance, higher refractive index, and better processability, and has UL94 V-0 flame retardant properties without the need for additives. However, polymethyl methacrylate is relatively cheaper than polycarbonate and can be used to produce large devices through bulk polymerization. Polycarbonate has poor wear resistance. Some polycarbonate devices used for wear-resistant purposes require special surface treatment.

PC Characteristics and Applications:

High tensile and bending strength, good impact toughness and creep resistance, high heat resistance, cold resistance and dimensional stability, high transparency, low water absorption, good insulation and processing formability, poor chemical stability, gaskets, sleeves, capacitors and other insulating parts; Instrument casing and protective cover; Manufacturing signal lights, windshields, cockpit covers, helmets, etc. in the aviation and aerospace industry.
