         Plastic chairs are generally recommended PP or PE, PP some of the more better quality. Buy it thick, the color is not too bright, strengthen the ribs (support tendons) thick.
    PP plastic:
    Copolymer type PP materials have lower heat distortion temperature (100 ° C), low clarity, low gloss and low stiffness, but have stronger impact strength and PP impact strength increases with ethylene content . Vicat softening temperature of PP is 150 ℃. Due to the high degree of crystallinity, the plastic chairs and chairs made of this material have very good surface stiffness and scratch resistance. PP does not exist environmental stress cracking problems.
    The melt flow rate (MFR) of PP is usually 1 to 100. Low MFR PP material better impact resistance but lower ductility. For the same MFR material, the impact strength of the copolymer is higher than that of the homopolymer. Due to crystallization, PP shrinkage is quite high, generally 1.6 ~ 2.0%.
