Struktol® RP 28

Mixture of clear aliphatic resins to improve the homogeneity of elastomers of different polarity and viscosity. It is quickly absorbed during the mixing stage, reducing viscosity and allowing ease of incorporation of other ingredients. It reduces the tendency to bagging, improves the properties of calendering, increases the extrusion speed without increasing swelling in the head, green tactocity, hardens us during vulcanization nor hardness is considerably reduced in the presence of mineral oils. Suitable for clear compounds where the non-stained is specified.
