Medical infusion tube material, medical plastic bottle and an infusion tube material PP, PE and HDPE three, now all using PVC (polyvinyl chloride), is a kind of plastic, the infusion bottle is made of polyethylene or polypropylene plastic infusion tube is a medical non-toxic transparent soft PVC plastic or high performance polyolefin thermoplastic elastomer (TPE) material.

PVC, English referred to as PVC (Polyvinyl chloride), is a vinyl chloride monomer (vinyl chloride monomer, referred to as VCM) in peroxide, such as azo compound initiator; or in light, under the action of heat polymerization by free radical reaction mechanism of polymerization of polymers. Vinyl chloride homopolymers and copolymers of vinyl chloride called vinyl chloride resin.

PVC is white powder amorphous structure, the degree of branching is small, the relative density of about 1.4, the glass transition temperature of 77~90 DEG, 170 DEG C to decompose, the stability of heat and light, at 100 DEG C or after long time exposure to sunlight, will decompose and produce hydrogen chloride, and further autocatalytic decomposition, causing discoloration also, the physical and mechanical properties decreased rapidly, in the practical application must be added in order to improve the stability of heat and light stabilizer of the.

The molecular weight of PVC in industrial production in 50 thousand ~11 million range, with larger polydispersity of molecular weight increases with the decrease of the polymerization temperature; no fixed melting point, 80~85 C 130 C to begin to soften, the viscoelastic state, 160~180 C began to change into the viscous flow; have good mechanical properties, tensile the strength of about 60MPa, the impact strength of 5~10kJ/m2; have excellent dielectric properties.

PVC was the world's largest production of common plastics, widely used. It has been widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers and so on.

Thermoplastic elastomer TPE (Thermoplastic Elastomer) is a kind of material with high elasticity, high strength, high elasticity and injection molding. Nontoxic security, wide range of hardness, with excellent color, soft touch, weather resistance, fatigue resistance and temperature resistance, excellent processing performance, without curing, can reduce the cost of recycling, can be two times of injection molding, and PP, PE, PC, PS, ABS and other base materials the adhesive, can also be a separate molding.
