The endless possibilities of liquid silicone rubber

The growing popularity of LSR products can be explained by its range of exceptional properties. LSR compounds are highly durable and resistant to extreme temperatures and environments. They are strong, flexible and stable. They can be electrical and thermal insulators. They are highly inert, biocompatible and hypoallergenic. They can be produced in any imaginable colour. And from a production perspective, LSR items can be made in high volumes with fast cycle times, automated processes and little waste.

So, it’s easy to see why LSR products have become so popular in so many industries. LSR compounds are useful in the medical, cosmetics and food industries because they are non-reactive and non-toxic. In the automotive industry, their heat-resistance makes them ideal for use close to engines. They are useful in any application that involves electricity.

Quite simply, LSR is a material that can be used for an immeasurable number of applications – on condition that you consult with industry experts about its suitability and production.
