Sabic plastic pellets PC 940A-116 Flame Retardant Large Stock
Medium viscosity, flame retardant PC. Exceptional surface. Clear, tints and opaque colors.
Impact resistant, flame retardant, transparent, heat-resistant, and easy to form.
Transparent, semi transparent, opaque, color selectable, etc
PC is a colorless, transparent and indefinite thermoplastic resin. Bisphenol A and diphenyl carbonate are synthesized by transesterification and polycondensation.
Density: 1.18-1.22g/cm へ 3, with 10% GF added, an increase of 0.08g/cm へ 3
Heat deformation temperature: 135C, with GF added, it can increase by 10C
Melting point: not fixed, forming temperature: 230-320 ℃
Shrinkage rate: 0.5-0.7%, with GF added, the shrinkage rate will decrease
Absorption rate, 23 ℃ 0.35%, drying material 120 ℃, 3-4 hours
English name: Polycarbonate
Specific gravity: 1.18-1.20 g/cm3
Molding shrinkage rate: 0.5-0.8%
Forming temperature: 230-320 ℃
Drying conditions: 110-120 ℃ for 8 hours
Material performance
High impact strength, good dimensional stability, colorless and transparent, good coloring, good electrical insulation, corrosion resistance, and wear resistance, but poor self-lubrication, stress cracking tendency, easy hydrolysis at high temperatures, and poor compatibility with other resins.
Suitable for making insulated transparent parts and impact resistant parts for small instrument parts.
Forming performance
1. Amorphous material, good thermal stability, wide forming temperature range, and poor flowability. Low moisture absorption, but sensitive to water and requires drying treatment. The forming shrinkage rate is small, which is prone to melting cracking and stress concentration. Therefore, the forming conditions should be strictly controlled, and the plastic parts must undergo annealing treatment.
2. For plastic parts with high melting temperature, high viscosity, and greater than 200g, it is advisable to use a heated extension nozzle.
3. The cooling speed is fast, and the mold pouring system should follow the principle of being thick and short. It is recommended to set up a cold material well, the gate should be large, and the mold should be heated.
4. If the material temperature is too low, it will cause material shortage, resulting in a dull plastic part. If the material temperature is too high, it is easy to overflow the edge, and the plastic part will bubble. When the mold temperature is low, the shrinkage rate, elongation rate, and impact strength are high, while the bending, compressive, and tensile strength are low. When the mold temperature exceeds 120 degrees, the plastic part cools slowly and is prone to deformation and sticking to the mold.
