How Does LSR Compare to Other Rubber Elastomers?

LSR is received in a liquid received and received in two parts. HCR materials are available as compounds and already pre-mixed and partially vulcanized.

The LSR liquid injection molding process is a very accurate and stable process. After passing through multiple cold runner systems, the compound is pushed into a heated cavity, which is where the vulcanization occurs. The cold runner technology removes material waste. Cooling the material enables the production of LSR parts with almost no material waste, eliminating the need for trimming operations and resulting in significant material cost savings. 

Comparatively, HCRs are processed via transfer molding in a high-cavity press mold. As a result, there is less material control and consistency, leading to higher part variability. HCR materials are also processed at higher temperatures and need a longer vulcanization time, making them less energy efficient and less environmentally friendly.

LSR adheres to plastics and metals, making it the ideal material for the two-shot and multi-shot LSR injection molding technology. This process enables consistency, a superior bond,  and ensures that each component will demonstrate the required performance and characteristics.

The Advantages of Liquid Silicone Rubber Moulding:

LSR is particularly popular for products for the Medical and Automotive industries, due to its good physical properties that include:

·A wide temperature range (–50 up to +250 °C)

·Very good temperature stability and resistance

·Excellent physiological/Hypoallergenic properties

·Good ageing and weather resistance (Ozone- and UV-resistant)

·Very good dielectric properties

·Good clarity/transparency and easily pigmentable if required

·Low viscosity that allows the material to flow easily into thin and complex areas of the mould

·Suitable for high-volume production

·Short cycle times compared to compression moulding (higher production rates)
