Description

[3A Composites, Airex AG, Switzerland] A series of white rigid foamboards made of Polyvinyl chloride (PVC). The FOREX® product range has lightweight, stable sheet materials for a wide range of indoor and outdoor uses. The boards can be worked with methods and tools used for wood. The boards may be coated with optional Polyethylene (PE) protective film (none, one sided, or two sided PE coating available). One-sided PE is standard for Forex Classic.

Four grades of FOREX® are available:

  • FOREX® Classic: white, lightweight (density 0.7); standard product
  • FOREX® Print: white, economical (30% cheaper); less rigid and resistant than FOREX® Classic due to its lower density (0.5)
  • FOREX® Color: Tinted (yellow orange, red, green ,blue, dark blue, gray, black); density = 0.6; cannot be used outdoors
  • FOREX® Smart: PVC-free version made from polystyrene; density = 0.2; available as white or black

Synonyms and Related Terms

FOREX®; Forex®

Similar products include Sintra, Komacel

Applications

  • digital printing; screen printing; signage; lettering
  • displays; exhibition design
  • interior design; partitions/cladding; furniture
  • shop design/shop fitting

Personal Risks

  • Harmful to health when inhaling or ingesting dust and vapors during unpacking, sawing, grinding and thermoforming.
  • Ensure good ventilation and dust extraction on processing machines and at other places where dust may develop.
  • Hazardous thermal decomposition products: Hydrochloric acid (HCl), Carbon dioxide (CO2), Carbon monoxide (CO)
  • SDS sheet [1]

Collection Risks

AIC Wiki - British Museum -2013 -Oddy test - pass for permanent use Any plasticizers and stabilizers may phase separate and ooze from polymer resulting in the formation of an oily film, white bloom on the surface of the material. This coating may corrode metal or transfer to objects nearby. Greg Smith and Michael Samide report that some rigid, unplasticized PVC construction boards give off a sulfur containing heat stabilizer (2-ethylhexyl thioglycolate [2-EHTG]) that can tarnish silver (publication forthcoming). However, they also reported finding several specific brands of PVC construction board, namely Komacel (Kommerling) and e-PVC (3A Composites) are safe for use in exhibition casework as they do not contain 2-EHTG.
