Silicone Manufacturing

40 years of experience with silicone...

…definitely gives us an edge. Silicone molding and manufacture is a specialist area of Romar’s, and we are very, very good at it.

We understand how to manufacture a silicone product. We know how long to heat it for and how long to cool it for. We know how long to post-cure and how to make it stiffer or easier to stretch. We can pinpoint any material issues you have and we know how to achieve the outcome you need.

Our expertise in silicone manufacturing and our years of experience means we’ll get to the solution you need quicker than anyone else in the business.

World Class Silicone Quality

People come to us from all around the world because of the quality of our silicone moldings. The expertise within the Romar team is significant. There’s no problem we haven’t encountered and found a solution for.

Unlike plastic or solid metal, silicone changes shape. Other manufacturers tend to overspecify dimensionally without really understanding the nature of the product.

The tensile modulus and tensile strength are key. We modify the cure chemistry (cross-link chemistry) and the physical materials within to meet the required accuracy and surface finish.

Silicone Properties

There are key advantages to silicone manufacturing aligned with properties. Silicone rubber is extremely resistant to high and low temperatures (-50 °C to +250 °C; specialty grades: -110 °C to +300 °C) with only slight changes in physical properties between -50 °C and +180 °C.

Other typical properties include its resistance to chemicals and environmental influences, its lack of odor and taste (many grades conform to FDA regulations), its water-repellent surface, and its high transparency and good processability.

Many other properties can be modified with additives.
