Perfectly legible auxiliary agents to enhance overall performance and offer a better cost control in PVC industries.
PROFILE PVC FOR UPVC WINDOWS
PVC profiles are a kind of popular composite material used in construction and decoration industries due to its light weight, excellent tensile and compressive strength, good corrosion resistance and relatively low costs. Extrusion technology is general method to produce a variety of PVC profiles.
PVC profiles can be used to substitute for aluminum profiles and steel materials. This ensures wide applications and unique position of PVC profiles in construction and decoration industries.
PVC raw material constraints
PVC raw material, specifically PVC Resin, is not stable under high temperatures, starting to decompose and giving off HCL gas at above 100 centigrade.or high humidity and dust levels at storage locations. Badly decomposed PVC resins runs the risk of HCL corrosion to workers and makes the end products turn yellowish.
PVC Resin itself has low impact strength so that impact modifier should be added to enhance its impact performance. In addition, some PVC products are open to the outdoors, exposed to rather low temperature, which gives higher requirements for impact strength.
All these factors must be taken into account when selecting a proper solution.
The auxiliary agents for PVC pipes
Thanks to the well-developed workmanship and quality control, auxiliary agent series is a reliable solution which can be used to improve the heat stability, impact performance and processing smoothness directly, at the same time as offering low production costs.
Auxiliary Agent series offer a competitive solution for extrusion and injection generally used for PVC profile making.
Should the particular PVC profiles require higher flexibility or some certain color(s), the PVC additives in combination with plasticizers or pigments are recommended.
And finally, for the most extreme conditions (such as the extreme low temperature or corrosive liquids), the dosages of auxiliary agents should be adjusted accordingly: a reliable solution offering durable protection of PVC profiles.
