CPVC pipe extrusion process Chlorinated polyvinyl chloride resin (hereinafter referred to as CPVC) was successfully developed by BF Goodrich in 1958. It is a chlorinated product of polyvinyl chloride resin (PVC). The chlorine content of chlorinated PVC can be 57% to 64% to 75%, with the increase of chlorine content, the corresponding temperature resistance, rigidity, chemical resistance, flame
The difference between PVC-C fire special pipe and CPVC civil water supply pipe PVC-C special fire-fighting pipe is the term used in the new national spray regulations, that is, chlorinated polyvinyl chloride pipe, which is specifically for fire-fighting special plastic pipe. GB 50084-2017 "Specifications for the design of automatic sprinkler systems" and GB 50261-2017 "Specifications for the
How is UPVC pipe developed? UPVC pipe application field UPVC pipes and PE pipes are thermoplastic pipes. They have a common characteristic, and they are still recognized by most people in terms of application. What is the development of UPVC pipes? What are the applicable fields of UPVC pipes? Let's explain it to everyone, let's take a look. How is UPVC pipe developed? In August
Rigid PVC basic knowlege Rigid polyvinyl chloride, UPVC is also called rigid PVC. It is an amorphous thermoplastic resin made by polymerization of vinyl chloride monomer plus certain additives (such as stabilizer, lubricant, filler, etc.). But strictly speaking UPVC is hard PVC, but hard PVC is not UPVC. UPVC should be rigorous and scientifically discussed. UPVC should not contain or use plasti
Basic knowledge of UPVC pipe UPVC pipe uses polyvinyl chloride resin as a carrier, which has excellent characteristics such as accurate temperature sensitivity, timed melting, and rapid absorption of active ingredients of additives when weakening the gravitational force between resin molecular chains. At the same time, it uses the world-famous calcium and zinc composite heat stabilizer. In the pr
The following is the reference formula of PVC water supply pipe as follows: 1. PVC 100, calcium and zinc stabilizer 3.5, light calcium 5, PE wax 0.15, stearic acid channel 0.2, CPE 3-6, ACR (401) 1.0-2.0, titanium dioxide 2-4, whitening agent proper amount. 2. PVC 100, calcium zinc stabilizer 2.4, paraffin wax 0.1, PE wax 0.13, stearic acid 0.3, monoglyceride 0.3, CPE 4, ACR (400 or 90S) 1.0, li
【Practical】 Formulation design of rigid PVC drainage pipe UPVC pipe is also called rigid PVC pipe. It is an amorphous thermoplastic vinyl chloride resin by adding certain additives (such as stabilizers, lubricants, fillers, modifiers, etc.), and then processed into a pipe by an extruder. Rigid PVC drainage pipe (UPVC) Advantages: light weight, corrosion resistance, high strength, can be r
