The semiconductor industry lives - and dies - by a simple creed: smaller, faster and cheaper. The benefit of being tiny is pretty simple: finer lines mean more transistors can be packed onto the same chip. The more transistors on a chip, the faster it can do its work.

NES understands the semiconductor industry is highly cyclical and can experience significant peaks in demand and we recognise the need for us to be agile and responsive if we are to remain as one of the major polymer suppliers into this demanding sector. Supplying high purity, quality critical products for high vacuum semiconductor applications, we are dedicated to providing advanced sealing solutions for some of the world's most demanding and quality critical customers.

With more than 30 years of experience in developing and manufacturing polymer sealing components, NES has built an impressive knowledge base and in-depth understanding of the unique and specific requirements of each market we serve. This ensures that our polymer sealing solutions meet all legislative and manufacturing performance standards.
