| Tecnoflon® VPL 85540 and 55540 belong to a brand new generation of very low temperature peroxide curable FKM. They have been designed to offer outstanding low temperature flexibility (i.e. TR10 = -40°C). Like all other Tecnoflon® peroxide curable grades, they exhibit excellent processability and superior mechanical properties and sealing ability; moreover they need very short post curing cycles. Some of the basic properties of Tecnoflon® VPL 85540 and 55540 are: Outstanding low temperature behavior Very good chemical resistance Low post cure Superior mold flow Lack of mold fouling Excellent mold release Very good chemical resistance Solvay offers medium (VPL 85540) and low viscosity (VPL 55540) versions in order to fulfil all customer’s requirements. Accordingly to the curing technology, Tecnoflon® VPL 85540 and VPL 55540 can be transformed by all the molding techniques, including injection, injection-compression, compression and transfer molding. Tecnoflon® VPL 85540 and 55540 can be used with all typical peroxide curing system and the other fluoroelastomer compounding ingredients. Mixing can be accomplished with two-roll mills or internal mixers. This material can be extruded into hoses or profiles or can be calendered to make sheet stocks or belting.&& |
