Renewable raw materials – the future of plastic enclosures

After comprehensive tests with many different types of biomaterials, OKW selected the BIOGRADE C7500 plastic produced by FKuR Kunststoff GmbH. This is obtained from almost 100% renewable raw materials – the initial products are cotton or wood. At the start of the process, the purified cellulose is esterified to obtain cellulose acetate (CA), which is then only slightly modified. This material has similar properties to ABS and can be processed using the normal injection moulding method.

For indoor applications there are no restrictions to the life cycle of the enclosure. The heat distortion temperature is as high as 123°C. Customer-specific colouring is also possible through the use of 15 natural dyes.

Parts made of BIOGRADE are biodegradable. After the biomaterial has been crushed mechanically, it is broken down into its non-toxic initial products by micro-organisms. If it is to be utilised thermally at the end of its useful life, this also guarantees carbon-neutral energy.

The environmental advantages of this recycling method are clear. However, bioplastics have not only ecological advantages, they also help to preserve raw material deposits and reduce dependence on petroleum.

Customers can now request most standard OKW enclosures in bioplastic material. A minimum order quantity applies.
