From 2008 Sundow began to produce CPVC resin in small scale. And in 2014, Sundow invested a huge money building a new producing line with annual capacity of 15000 MT, this new producing line adopt new technology, equipped with 25 M3 reactor and advanced DSC automatic control system, all this ensures Sundow Surpla™ CPVC resin quality has a great improvement compared with the old technology, especially some properties such as heat stability, processibility, gelation, vicat softening temperature.
According to end users evaluation, Surpla™ CPVC resin is reaching the same quality level as the international top famous CPVC resin brands. Now Surpla™ CPVC resin and compound are exported to many countries such as India, USA, Mid-East, Korea etc, successfully replacing several world famous CPVC resin brands.
Surpla™ CPVC resin and compound are tested strictly according to GB or ASTM standard. In order to better test and verify Surpla™ CPVC resin/compound quality and quality consistency, Sundow invested a big money buying expensive test machines such as Brabender Rhometer for more accurate analysis; each lot will be tested and checked by Brabender Rhometer for gelation and heat stability.
Sundow is also equipped with CPVC pipe extrusion line and injection machine, CPVC resin for export will be formulated and extruded or molded in such machines to ensure that the exported materials have no problem not only on physical property, but also on the processability and mechanical properties.
Based on high quality CPVC resin and rich knowledge in CPVC compounding formulation, Sundow also has a mixing unit with capacity of 5000 mt per year, producing CPVC compounds for the applications such as hot water pipe, sprinkle pipe, pipe fitting etc.
What is SurplaTM CPVC resin
CPVC is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) resin, which is significantly more flexible and can withstand higher temperature than PVC. It is a high heat and corrosion resistant material, and it has become an important engineering thermoplastic due to its relatively low cost, high heat distortion temperature, chemical resistance, outstanding mechanical, and dielectric, flame and smoke resistance 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. Uses include hot and cold water delivery pipes and industrial liquid handling. 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.

Table 2 the Selection Guide of CPVC Resin
Grade | Characteristics | Application |
IJ-550 | best flowability | it is mainly used for injection molding |
ET-750 | lower chlorine, its vicat softening temperature is lower than other grades; good processing ability and good surface | extrude of all kinds of heat-resistant plastic products, such as hot-water tube used in shipping and life facilities, brine tube, chlorine gas tube, electric pipeline of chlorine-alkali factories etc |
ET-800 | the general grade | extrude of all kinds of heat-resistant plastic products, such as hot-water tube used in shipping and life facilities, brine tube, chlorine gas tube, and electric pipeline of chlorine-alkali factories |
ET-850 | highest chlorine and highest vicat softening temperature | Extrude of all kinds of heat-resistant plastic products where the highest vicat softening temperature is required. |
