We are offering here the Plastic Bristle that are highly durable plastic that are coated with abrasive grit for aggressive cleaning. They are chemical-resistant plastic. Commonly used on sidewalks and driveways, these brooms have stiff bristles that can move heavier debris than brooms for smooth surfaces. A durable steel strip locks in bristles without the added weight of a wood or plastic block. Its stiff aggressive properties make it ideal for utility brushes, coffee urn brushes, deck scrub brushes, floor and garage brushes. Polystyrene bristles wear longer, perform better, and yet carry a comparable price tag to natural bristles. Plastic Bristle is very efficient.
