As a transparent PC plastic candle cup, first of all, it must ensure high transparency, secondly, strength, impact resistance, abrasion resistance, heat resistance, chemical resistance, water absorption are better. Only in this way can the transparency requirements be met in use. For the selection of transparent plastics, PC plastic is an ideal choice, but its price is high the injection molding process is difficult, so PMMA is often used, PPE has to be stretched to obtain good mechanical properties, so it is mostly used in packaging containers. use. PC plastic has high viscosity, high melting temperature poor fluidity. It must be injection molded at a higher temperature (between 270 320℃). Relatively speaking, the temperature adjustment range of the material is narrow the manufacturability is as good as PMMA.

The advantages of the material of "PC plastic candle cup" are 1. High strength elastic coefficient, high impact strength, wide temperature range of use; 2. High transparency free dyeability; 3. Low forming shrinkage good dimensional stability; 4. , Good fatigue resistance; 5. Good weather resistance; 6, Excellent electrical properties; 7. Tasteless odorless, harmless to the human body, in line with hygiene safety.

a. Mechanical properties: high strength, fatigue resistance, dimensional stability, small creep (very little change under high temperature conditions); b. Heat aging resistance: the enhanced UL temperature index reaches 120~140℃ (outdoor Long-term aging is also very good); c. Solvent resistance: no stress cracking; d. Water stability: easy to decompose in water at high temperatures (use caution in high temperature high humidity environments); e. Electrical properties: 1. Insulation Performance: Excellent (It can maintain stable electrical performance even under humidity high temperature, is an ideal material for manufacturing electronic electrical parts); 2. Dielectric coefficient: 3.0-3.2; 3. Arc resistance: 120s; f. Forming processability: ordinary Equipment for injection molding extrusion. Is the performance of the plastic candle cup PC material
