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; PE film on one side
- FOREX® Print: white, economical (30% cheaper); less rigid and resistant (density=0.5); PE film on one side
- FOREX® Color: Tinted (9 colors); density=0.6; cannot be used outdoors; PE film on one side
- FOREX® Smart: PVC-free version made from polystyrene; density=0.2; available as white or black
Synonyms and Related Terms
FOREX®; Forex®; PVC Board
Similar products include Sintra (3A Composites), Komacel (Kommerling), Komatex (Kommerling)
For comparison with alternates, see PVC Boards.
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 link
Collection Risks
Research by 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 [1]. 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.
