Primasil are the largest independent silicone rubber manufacturer in the UK, and are one of Europe's leading suppliers of sil ... icone rubber products and compounds. Our business activities cover four main areas: 1. The development and supply of silicone rubber compounds (the ‘raw material’ of silicone manufacture). 2. The development and manufacture of silicone rubber products (mouldings, extrusions, fabrications, etc), principally for sale to finished article manufacturers. 3. The manufacture of non-silicone rubber products, at our wholly owned subsidiary in the Czech Republic. 4. The development of silicone rubber products, from inception to high volume production. Our customers represent all industries, including aerospace, automotive, consumer products, defence, electronic, domestic heating, medical & pharmaceutical, oil & gas, transportation, and so on. Primasil products are used across the globe. This reflects our ability to develop materials that exactly match our customer' requirements rather than use 'best fit' alternatives. Of course, all the relevant QA certifications and approvals are in place. read more
