Lightweight student tr90 frames are characterized by good flexibility
- Jul 26, 2018 -

Lightweight student tr90 frames are characterized by good flexibility, rubber-like elasticity, good flexibility at -50 ° C, good transparency and surface gloss, good chemical stability, anti-aging and resistance Ozone is strong and non-toxic. It has good blending property with filler, and has good coloring and molding processability. In general, the performance of lightweight student tr90 frames depends mainly on the content of lightweight student tr90 frames on the molecular chain. Due to the adjustable composition ratio of lightweight student tr90 frames to meet different application needs, the higher the content of lightweight student tr90 frames, the higher the transparency, softness and toughness.

The polymerization method uses high pressure bulk polymerization, solution polymerization, emulsion polymerization, suspension polymerization. Lightweight student tr90 frames with more than 30% emulsion polymerization, lightweight student tr90 frames low content with high pressure bulk polymerization.

Lightweight student tr90 frames and lightweight student tr90 frames have a large relationship with molecular weight and melt index. When the melt index is constant and the content of the lightweight student tr90 frames is increased, the elasticity, flexibility, compatibility, transparency, etc. are also improved. When the VAC content is reduced, the performance is close to that of polyethylene, the rigidity is increased, and the wear resistance and electrical insulation are improved. If the VAC content is constant, the melt index decreases, the softening point decreases, the workability and surface gloss improve, but the strength decreases. Otherwise, the molecular weight increases, the impact performance and the environmental stress crack resistance with the decrease of the lightweight student tr90 frames. improve. The polarity of lightweight student tr90 frames increases elasticity and viscosity, decreases crystallinity and electrical properties, and is soluble in hydrocarbon solvents and oils.
