Description

Sintra Construct
Credit 3A Composites

[3A Composites USA] A registered trademark for a lightweight rigid, expanded Polyvinyl chloride board with matte PVC film on each surface. Sintra® was introduced to North America in 1980. It has been used for the construction of signs and exhibits, screen painting, and as a substrate for mounting photographs.

Four grades of Sintra® are available:

Sintra: standard product; Bright white, lightweight, low gloss (satin), printable on both sides
Sintra Eclipse: two layer: Bright white face over black; both with same characteristics as standard Sintra
Sintra Vers (formerly called ePVC): lighter weight, general purpose, low-gloss finish
Sintra Construct: Designed for machinability with extra rigidity and screw retention; available in thick gauges

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 (now renamed as Sintra Vers, 3A Composites) are safe for use in exhibition casework as they do not contain 2-EHTG.
