TUBING [PVC Tubing]

Flexible non-toxic PVC transparent tubing. Sold in 10-metre lengths. (*11mm tubing only is sold per metre.)

(Wikipedia excerpt: "...Polyvinyl chloride (alternatively: poly(vinyl chloride),[6][7] colloquial: vinyl[8] or polyvinyl; abbreviated: PVC[8]) is the world's third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene). About 40 million tons of PVC are produced each year.[9] PVC comes in rigid (sometimes abbreviated as RPVC) and flexible forms. Rigid PVC is used in construction for pipes, doors and windows. It is also used in making plastic bottles, packaging, and bank or membership cards. Adding plasticizers makes PVC softer and more flexible. It is used in plumbing, electrical cable insulation, flooring, signage, phonograph records, inflatable products, and in rubber substitutes.[10] With cotton or linen, it is used in the production of canvas.

Polyvinyl chloride is a white, brittle solid. It is soluble in ketones, chlorinated solvents, dimethylformamide, THF and DMAc.[11] Polyvinyl chloride is produced by polymerization of the vinyl chloride monomer (VCM), as shown.[15]
The polymerisation of vinyl chloride. About 80% of production involves suspension polymerization. Emulsion polymerization accounts for about 12%, and bulk polymerization accounts for 8%. Suspension polymerization produces particles with average diameters of 100–180 μm, whereas emulsion polymerization gives much smaller particles of average size around 0.2 μm.

PVC may be manufactured from ethylene, which can be produced from either naphtha or ethane feedstock.[16]  ...")
