Silopren LSR®1640 is a two-component liquid silicone rubber for injection molding processes.LSR 1640 shows in comparison to LSR 1640 a higher productivity, higher transparency, less yellowing and low volatile contents. With this low viscosity LSR, it would be possible to increase productivity by reduce injection time and total cycle time. Also, it is easier to inject into the cavity of the mold which is more complicated designed. In addition, higher transparency and less volatile content make it most suitable for consumer products.

Key Features and Benefits
Vulcanisates consisting of LSR 1640 are distinguished by the following properties:

High flowability, low viscosity and short injection time.

Low volatiles content

Fast cure

Excellent mold release

Excellent Thermal stability

Good rubber-like properties

Excellent compression set

Excellent resilience

High stability to ozone and ultraviolet light

Outstanding resistance to ageing

Not readily combustible, does not melt or drip

Easy-pigmentable with LSR Colour Pastes fulfill the requirement of KTW

Potential Applications
Because of the outstanding properties,LSR 1640 is particularly suitable for the following elastomeric articles: sealing elements, O-rings, stoppers, diaphragms, keypads, bellows, vibration dampers, air vent flaps, switch covers, pressure cookers parts, cable connectors s.o.
