The Institute of Scrap Recycling Industries (ISRI), Washington, has updated its Scrap Specifications Circular to include new specifications for flexible polyvinyl chloride (PVC) scrap. The new specifications were approved at the ISRI Convention Board and Governance Meetings April 16, 2018.
This specification addition is intended to more accurately reflect the plastic scrap commodities currently being traded in the marketplace, ISRI says. It is part of an ongoing effort by ISRI’s Plastics Division to provide the tools needed to trade in multiple grades of plastic resin. This specification, along with the recently developed rigid PVC specification,further expands the breadth and depth of the plastics section of ISRI’s Scrap Specifications Circular, which provides specifications for postconsumer and postindustrial plastics. The new flexible PVC specification can be found on page 42. It bears this description: “Typically consists of molding, weather stripping, flexible tubing, purging, battery covers, medical tubing, auto decals, flexible films and sheeting. It is typically resistant to chemicals, nonporous and extruded. It can be found in long profiles and can be wound onto a reel.”
Prohibitives are polyethylene terephthalate (PET) of any form and medical and hazardous waste, while contamination allowed at small percentages includes plastics other than PVC, such as high-density polyethylene terephthalate (HDPE), low-density polyethylene (LDPE), polypropylene (PP) and polystyrene (PS); rigid PVC; liquids; paper and cardboard; metals; glue, adhesives and sticky tape; co-extruded materials; and reinforcement weaves and fabrics.” ISRI plastic specifications Scrap Specifications Circular
