Description and Uses
Para-tertiary-butylphenol formaldehyde resin (PTBPF- R) is a polycondensate of para-tertiary-butylphenol and formaldehyde. Major occupational sources are neoprene glues and adhesives in industry, in the shoemaking and leather industry or in car production. It is also used as a box preservative in box and furniture manufacture, and in the production of casting moulds, car-brake linings, insulated electrical cables, adhesives, printing inks and paper laminates. Para-tertiary-butyl-phenol is the sensitizer.
Polycarbonate Chain Terminator, Glycidyl Ethers; Phosphate Esters, Fragrances, Oil Field Chemicals-Demulsifiers; Plasticizer for cellulose acetate; intermediate for antioxidants, special starches, oil-soluble phenolic resins; pour-point depressors and emulsion breakers for petroleum oils and some plastics; synthetic lubricants; insecticides; industrial odorants; motor-oil additives.
