POLYTONE AP 121 is a non heat reactive thermoplastic alkyl phenolic resin designed to develop high tack levels in rubber compounds which are used in tyre construction and mechanical goods. This resin provides tack in elastomers that are usually difficult to tackify. POLYTONE AP 121 is used as tackfier in the manufacture of rubber goods such as in tire industry and in the manufacture of mechanical goods.
POLYTONE AP 121 is soluble in esters, ketones, aromatic and aliphatic chlorinated hydrocarbons. Insoluble in alcohols. Compatibility Excellent compatibility in synthetic and natural rubbers. Blends easily into rubber stocks.
Available in 25 Kg bags.
Store under cool dry conditions. It is recommended that the material be used within 12 months from the date of manufacture.
