TPX Pepper Ball is the only crystalline polymer plastic ball in the commercialized high transparency resin. TPX plastic ball has a large shrinkage rate and good light transmittance, which can reach 90% ~ 92%. TPX plastic ball is environmentally friendly and safe, and can be used in food and medicine fields.1. Comparison of ⒈TPX pepper balls at high temperature: quite high elongation at break, impact strength and excellent creep resistance (high rigidity); 

A, TPX plastic ball exceeds PP plastic ball above 100℃;

B, TPX pepper balls can be used for one year at 130℃;

C, TPX pepper ball exceeds PC plastic ball above 150℃;

D, TPX pepper ball can be used for 100 hours at 180℃.1. Electrical insulation of TPX pepper ball: (nonpolar group in TPX molecule)A. Dielectric strength of TPX pepper ball: 65KV/mm (better than PTFE and propylene);B, the dielectric constant of TPX pepper ball: 2.12(PTFE dielectric constant is 2.0 ~ 2.1);3. Chemical resistance of TPX pepper ball: acid, alkali and edible oil; Low water absorption: extremely high tolerance to water and steam.1. Hygienic safety of ⒋TPX plastic balls: non-toxic, in line with the US FDA certification;The electrical insulation of TPX pepper balls is better than that of polypropylene. Acid and alkali resistance, chemical corrosion resistance, organic solvent resistance, stress cracking resistance, and no tendency of stress cracking of other transparent materials under the action of detergent when used.TPX pepper balls can be cooked and sterilized at 130℃ for 400 times without fogging, sterilized by hot air at 160℃ for 50 times in one hour, and sterilized at above 200℃. It can also be sterilized by ethylene oxide and radiation.Disadvantages: poor environmental resistance, easy oxidation, degradation by radiation after illumination, heating and yellowing.Suitable for transparent medical equipment, microwave tableware and ordinary tableware.TPX pepper ball also has good fiberization and wide sources of raw materials, so some people call it "poor nylon".Injection characteristics TPX is a crystalline polymer with obvious melting point, which can be melted when heated to 235℃. When injection molding, the temperature is generally 260℃-300℃.TPX pepper balls don't absorb water, so they generally don't need to be dried. Sometimes, for the sake of product quality, they can be dried at 60℃ for 30 minutes to 1 hour to drain the floating water in the raw materials.The shrinkage rate of TPX pepper ball is 22 ‰;
