PP plastic sheet processing is made from PP resin adding various functional auxiliaries through extrusion, pressing, cooling, cutting, etc. PP plastic sheet is a semi-crystalline material. It is tougher than PE and has a higher melting point. Due to the PP homopolymer type temperature above 0 ℃ above is very fragile, so many business of PP material is 1 ~ 4% or higher ratio of ethylene content in random copolymer of ethylene copolymer of pliers. Copolymer of PP materials with low heat distortion temperature (100 ℃), low transparency and gloss, low rigidity, but there are have stronger impact strength.

PP plastic processing has excellent impact strength, good dimensional stability and good dyeing, processing and mechanical processing, high mechanical strength, high stiffness, low water absorbability and good corrosion resistance, simple connection, non-toxic tasteless, has excellent chemical properties and electrical insulation properties. It can resist heat and deformation, and it has high impact toughness under low temperature. It is also a kind of hard PVC plastic sheet processing, not easy to scratch, not easily deformation material. Low water absorption; High dimensional stability.

The conventional PP plastic plate is not very white plastic plate processing, but the toughness is very good, can be cut with the cutting machine, also can open the die. PP plastic sheet processing temperature: from -50c to + 70C. Among them, transparent PP plastic plate is very transparent, and the polishing and polishing effect is excellent for PP plastic plate processing, which is the preferred material for replacing PC board. Compared with acrylic, it has excellent toughness.

PP plastic processing is not affected by the influence of water, inorganic salt, alkali and acid, but soluble in ketones, aldehydes and chlorinated hydrocarbons in the plastic processing equipment, corroded by ice acetic acid, vegetable oil, such as yield stress cracking. The resistance of ABS is poor, and it is easy to degrade under ultraviolet light. After six months outdoors, the impact strength drops by half.
