| H7125
(hydrogenated) H7311 (hydrogenated) |
Hydrogenated grades of HYBRAR™ 7000 series (Vinyl-rich SEPS or SEEPS) have excellent heat and weather resistance. HYBRAR™ shows an excellent miscibility with polypropylene resulting in exceptional transparency and clarity when blended. Flexible film manufactured using HYBRAR is more environmentally friendly alternative to PVC due to the absence of harmful plasticizers. These films also have a much lower environmental impact during production and disposal than PVC. Additionally, the hydrogenated (7000 series) material is resistant to weathering and yellowing and has great miscibility with polypropylene. It can be used in films, sheets, extruded parts (pipes, cables), injection molded parts and other products. |
