PVC soft and hard co-extruded
PVC soft and hard co-extruded
Product Details

PVC soft and hard co-extruded seal, PVC profile is added by the PVC resin a variety of functional additives, after high temperature extrusion molding of industrial and living PVC products. According to the performance of PVC soft and hard co-extruded seal can be divided into hard And soft two kinds of hard PVC profiles are used for construction, such as the production of PVC doors and windows, PVC flooring, PVC pipe, etc .; soft PVC profiles for PVC hoses, transmission cables, etc. Added auxiliaries of PVC profiles with Anti-aging, anti-ultraviolet, corrosion-resistant, high strength, cheap, can be part of the alternative aluminum, steel and so on.
PVC: low molecular weight soluble in ketones, esters and chlorinated hydrocarbons and other solvents. High molecular weight insoluble. Polyvinyl chloride resin by molding to get PVC plastic. The monomer cost is low, the production process is mature However, the thermal stability and light resistance is poor .140 ℃ decomposition of hydrogen chloride release, in the process of forming the molding process, the need to join the stabilizer. Softening temperature is low. , Limited to 80 ° C below. According to the amount of plasticizer added, can be made of soft plastic and hard resin. Soft plastic can be used as wire and cable sheath and other insulating materials, can be made transparent film, used as Raincoats, tablecloths, agricultural seedling film, etc .; also used to make artificial leather, foam and polyvinyl chloride fiber. Rigid plastic can be used in the system plate, pipe, storage tank, absorption tower, etc. Vinyl chloride by suspension polymerization can be powder resin , If the emulsion polymerization method, available paste resin.
Decorative pressure is made of flexible, highly plastic PVC or with good elasticity and anti-compression deformation, anti-aging, ozone, chemical effect, wide use of temperature range (-40 ℃ ~ +120 ℃) ​​of EPDM rubber (EPDM) decorative materials, containing a unique metal fixture and tongue-shaped buckle, durable.
