The characteristics of PP Polypropylene Pan Head Slotted Screws are as follows:

1, physical properties: PP (polypropylene) is a non-toxic, odorless, tasteless milky white, highly crystalline polymer with a density of 0.90-0.91g/cm3, exceptionally stable to water, 24 hours in the water absorption of 0.01%, the molecular weight of 8-15 million between. The molecular weight is between 8-15 million. It has suitable molding properties, but the shrinkage rate is significant, and it is easy to make thick-walled products with depression. The product's surface gloss is good and easy to color.

2, mechanical properties: PP (polypropylene) of high crystallinity structural regularity has good mechanical properties, its strength, and hardness, elasticity is relatively good, but at room temperature and low temperature, the impact strength is poor, the molecular weight increases, the impact strength is also increased, but molding and processing performance deterioration. PP (polypropylene) Pan Head Slotted Screws The most prominent performance is the resistance to bending fatigue. The most outstanding property of PP (Polypropylene) Pan Head Slotted Screws is resistance to flex fatigue. The dry friction coefficient is similar to nylon's but not as good as that under lubricating oil.

3, thermal properties: PP (polypropylene) has good heat resistance, a melting point of 164-170 ℃, made of PP Plastic Pan Head Slotted Screws can be sterilized at temperatures of more than 100 ℃ for sterilization of medical equipment used; in the absence of external forces, 150 ℃ does not deform—embrittlement temperature of -35 ℃.

4, chemical stability: PP (polypropylene) Pan Head Slotted Screws of chemical stability is very good. In addition to concentrated sulfuric acid and concentrated nitric acid erosion, various other chemical reagents are relatively stable. Still, low molecular weight aliphatic hydrocarbons, chlorinated hydrocarbons, etc., can make the PP (polypropylene) soften and dissolve.

5, electrical properties: PP (polypropylene) high-frequency insulation is excellent because it almost does not absorb water, so humidity does not affect insulation properties. PP (polypropylene) Pan Head Slotted Screws have a high dielectric coefficient, with the temperature rise, can be used to make heated electrical insulation products connected to the fastening, and its breakdown voltage is also very high. PP (polypropylene) voltage and arc resistance are good. PP (polypropylene) voltage and arc resistance are good, but the degree of static electricity and copper contact are easy to age.

6, weathering: PP (polypropylene) is very sensitive to ultraviolet light, adding zinc oxide, bis(2-month) laurel thiopropionate, carbon black or similar opalescent fillers can improve the PP Plastic Pan Head Slotted Screws aging resistance.
