U.S. Co-extruded New Technology for Color Plastic Profiles Causes Wide Attention

On September 26th, at the 2002 annual meeting of the national plastic profile and door and window products industry held in Beijing, the United States General Electric Company introduced the new technology of resin and PVC as co-extruded materials for the production of color plastic profiles in the Chinese market. extensive attention. Beijing Wanhua Fuhua Chemical Co., Ltd. cooperated with General Electric of the United States to actively promote this technology and set up demonstration enterprises in various places.
GELOYRASA resin is a ternary polymer composed of acrylonitrile, styrene and acrylic rubber. It is similar to ABS in many aspects and inherits many advantages of ABS. The only difference is its rubber modification composition. GELOYRASA resin replaces butadiene rubber with acrylic rubber to avoid the instability of butadiene rubber. It is an excellent engineering plastic with high weatherability, high gloss, high corrosion resistance, high heat resistance, and easy processing.
In the United States, General Electric's GELOYRASA resin has a history of practical application for nearly 20 years, and has a wide customer base in the architectural decoration industry, automotive industry, horticulture industry, and electronics industry. The color plastic steel profiles produced by the coextrusion of GELOYRASA resin and PVC have extremely high weather resistance and rich and stable color. GELOYRASA resin heat-resistant temperature increased 20 degrees Celsius than PVC. GELOYRASA resin has excellent impact resistance at room temperature, can maintain 75% of the normal temperature impact resistance at minus 30 degrees Celsius. The common nature of GELOYRASA resin and PVC in many physical properties makes the production process of profiles and doors and windows very easy, the compatibility of the two is good, the thickness of the coextruded layer is stable, and in the situation of large temperature difference, the two will not be distorted, stratified and separated. No warping due to internal stress. The bumps and cuts during transportation and secondary processing do not cause large cracks and chippings in PMMA-PVC coextruded profiles. Therefore, GELOYRASA-PVC co-extruded profiles have low scrap rates and low costs.
The test proves that the requirement of coextrusion equipment for GELOYRASA-PVC coextruded color plastic steel profiles is not harsh. The existing PMMA-PVC and PVC-PVC coextrusion machines and molds of our manufacturers can be used to produce qualified products after appropriate technical transformation. GELOYRASA-PVC coextrusion technology is fully applicable to China's production technology and is a project with low risk, low investment, and high return. Beijing Wanhua Fuhua, GE Plastics, Futian Machinery and all its partners firmly believe that color profiles are the development trend of China's plastic steel profiles. As a result, the future steel profile market will no longer be a white world, GELOYRASA-PVC co-extruded color plastic steel profiles have the strength and the rise of the color aluminum profile ratio
