1. What is Surpla® CPVC?
Surpla® CPVC is a PVC homopolymer that has been subjected to a chlorination reaction. It has become an important engineering thermoplastic due to its relatively low cost, high heat distortion temperature, chemical resistance and outstanding mechanical, dielectric, flame and smoke properties. CPVC was first commercialized by Noveon in the early 1960s and has since proven its value in a variety of industrial applications in which a high use temperature and excellent resistance to chemical are desirable. Besides pipe and fittings, many other industrial fluid-handling product are available in CPVC including pumps, valves, strainers, tower packing, and duct, as well as sheet for fabrication into tanks, duct, and tank lining.

Brief Introduction of Sundow Polymers Co., Ltd.
Sundow Polymers Co., Ltd. is a high-tech chemical company that is focused on R&D, manufacturing and marketing of impact modifiers and processing aid. It is one of the industrial pioneers and leaders of Chlorinated Polyethylene (CPE), acrylic impact modifier (AIM), acrylic processing aid (AIP) and MBS impact modifier in China. It has been in the R&D of chlorinated polymers and acrylic products business over 13 years.
Sundow Polymers is located in the Yellow River delta development zone in the Shandong Province. It has two manufacturing facilities with over 150 acres. Currently it has four main product series with an annual capacity as follows: 50, 000 metric tons (MT) of CPE, 15000 MT AIM, 10000 MT AIP, 25, 000 MT MBS.
Because of our unique R&D experience in the chlorinated polymer business, we have currently developed 15 grades in the CPE series. These grades can be applied in the flexible and rigid plastic products, flame-retardant ABS, cable wire insulation and jacket, industrial and automobile hoses, magnetic rubber and various special purpose rubber products etc. These grades can be served for a variety of needs to our customers. Our product WELLPREN® CPE has gained high reputation among our domestic and international customers. WELLPREN® CPE is marketed to most major industrial leaders across 25 countries. Many world top window profile, wire/cable and FR-ABS manufacturers have been our regular customers.
Sundow has creative technology and advanced management for producing AIM and AIP, which is derived from former joint venture with a world class AIM/AIP producer. Sundow WELLPLA® AIM and AIP series products enjoy high reputation in China and now begin to March into the international top market.
Sundow represents its affiliate company for sale of MBS impact modifier in international market in the Sundow brand name of WELLPA® . WELLPA® Has 6 grades and is widely used in opaque and transparent products.
