Drop forged chains as well as double drag link chains can be equipped with plastic and/or steel scrapers. For heavy-duty use, either of these chains can be equipped with welded steel scrapers. With double drag link chains the outer link can also be L-bended.
Chains with plastic scrapers have quite a few advantages. The plastic scrapers are made of wearresistant nylon and are flexible. The fact that the chain rests on the plastic scrapers eliminates the steel-on-steel contact, which leads to saving energy and a considerable noise reduction. Plastic scrapers are temperature resistant between -20 °C and + 70 °C. The special zytel scraper is temperature resistant up to +110 °C. VAV also offers glass fiber enforced plastic scrapers which are more durable and less flexible. On your request VAV can also deliver an FDA quality scraper. The following table shows the various different types of plastic scrapers, together with the corresponding chain.
