Primasil Silicones Limited Factory

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.

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.

Primasil were the first independent silicone company in the UK to achieve ISO9001:2008 certification and we constantly check that we are meeting the customer requirements and that any potential problems are identified at the earliest possible opportunity. This ‘Right First Time’ mantra permeates all aspects of our organisation.
