What Is Accelerator TBBS (NS)? Accelerator TBBS, also called NS or NZ, CAS 95-31-8, chemically N-tert-butyl-2-benzothiazolesulfenamide, is a sulfenamide (delayed-action) rubber accelerator. It is the most widely used accelerator in the tyre industry, prized for its combination of excellent scorch safety and a fast, efficient cure. Like other sulfenamides, TBBS stays largely inactive at the

What Is Accelerator CZ (CBS)? Accelerator CZ, also known as CBS, CAS 95-33-0, chemically N-cyclohexyl-2-benzothiazolesulfenamide, is a sulfenamide (delayed-action) rubber accelerator. It is one of the most widely used accelerators in the rubber industry, above all in tyres, because it combines long scorch safety during processing with a fast, efficient cure once the temperature is

Antioxidant RD (TMQ) in Tires and Rubber Antioxidant RD (TMQ, CAS 26780-96-1) is an amine antioxidant used mainly in tyres and dark mechanical rubber goods, where it gives strong protection against heat, oxygen and flex-fatigue ageing. This page looks at how it is used in tyres and rubber, and how it fits alongside antiozonants. Why

Butylated Hydroxytoluene (BHT) in Rubber and Plastics Butylated hydroxytoluene (BHT, Antioxidant 264, CAS 128-37-0) is a hindered phenolic antioxidant used to protect rubber and plastics against oxidation and heat ageing. This page looks at its role in rubber and plastics specifically, and at how it compares with higher-molecular-weight phenolics. Why BHT in rubber and plastics?

Antioxidant 2246 in Rubber and Plastics Antioxidant 2246 (2,2′-methylenebis(4-methyl-6-tert-butylphenol), CAS 119-47-1) is a non-staining hindered phenolic antioxidant used to protect rubber and plastics against heat and oxygen ageing. This page looks at how and where it is used – in which polymers, at what stage, and why the non-staining property matters. Why 2246 in rubber

What Is Antioxidant RD (TMQ)? Antioxidant RD, CAS 26780-96-1, also called TMQ, is the polymerised form of 2,2,4-trimethyl-1,2-dihydroquinoline – an amine-type (quinoline) antioxidant. It is one of the workhorse antioxidants of the rubber industry, giving strong protection against heat, oxygen and flex fatigue ageing. It is used mainly in tyres and heavy mechanical rubber goods.

What Is Butylated Hydroxytoluene (BHT)? Butylated hydroxytoluene (BHT), CAS 128-37-0, chemically 2,6-di-tert-butyl-4-methylphenol (also called Antioxidant 264 or DBPC), is a hindered phenolic antioxidant. It is one of the most widely used antioxidants in the world, protecting rubber, plastics, oils, fuels and other organic materials against oxidation and heat ageing, and is also used as a

What Is Antioxidant 2246? Antioxidant 2246, CAS 119-47-1, chemically 2,2′-methylenebis(4-methyl-6-tert-butylphenol), is a hindered phenolic (bis-phenol) antioxidant. It protects rubber, plastics and other organic materials against heat and oxygen ageing – the gradual degradation that makes a polymer harden, crack, discolour or lose strength over time. Antioxidant 2246 is a non-staining, non-discolouring antioxidant. Because it does

PVP K90 in Adhesives and Coatings Polyvinylpyrrolidone K90 (PVP K90, CAS 9003-39-8) is a high-molecular-weight, water-soluble polymer used as a film-forming binder and thickener in adhesives and coatings. Its combination of solubility in water and in many polar organic solvents, clear film formation and strong adhesion makes it useful where a single binder has to

Phosphoric Acid Price and Supply: What Drives the Cost Phosphoric acid is a high-volume commodity, and its price swings with the phosphate-rock and energy markets – and with the process route (wet or thermal). This page explains the cost structure and how to buy well, without quoting prices (which change with the feedstock cycle). 1.
