About the company

High quality, customer-oriented service and over 200 years experience and development in the field of fiber processing

We process a glass fiber produced especially for us for polishing, erasing, brushing and grinding products.

With over 200 years of experience and development in the field of fiber processing and customer-oriented service, we are today a leader in this field.

The glass fiber made exclusively for our purposes is not identical to the general known glass fibers. It is manufactured without CFCs. Due to its fiber diameter, it can not be inhaled and is therefore in a health-safe area. It was therefore not included in the group of dangerous substances.
