Our 'can-do' attitude has been key to our growth

Primasil was founded in 1978 to meet industry’s growing requirement for silicone rubber.

Originally a moulding company, Primasil soon expanded to offer extrusion and develop their own custom formulations, quickly becoming the leading independent UK supplier of silicone rubber compounds.

In March of 2022, Primasil was acquired by Minnesota Rubber & Plastics. The Primasil team looks forward to working alongside our new colleagues at Minnesota Rubber and Plastics to continue serving our valued customers – in Europe and around the globe – with innovative technologies, great talent and more options than ever before.

Today, Primasil continues to supply silicone products and materials all over the world to many different industries, including the quality led medical industry using the brand name "Medisil".

Based on a ‘can do’ attitude, Primasil has succeeded with challenging products where other companies have failed. This had led to many successful long-term partnerships with a diverse range of customers – from small local manufacturers to the largest multinationals.
