1、 ENGINEERING STANDARDS Material Specification EDS-M-6069 Plastic Roll Goods Copyright 2011 General Motors Company All Rights Reserved December 2011 Originating Department: GM Korea Engineering Standards Page 1 of 18 Version: 1 1 Scope 1.1 Material Description. Plastic Roll Goods (PRG) consist of two

2、 basic construction types, Supported and Unsupported. Plastic Roll Goods (PRG) materials shall be compounded to be flexible, free from tackiness, and compatible with other PRG materials and coated genuine leather. Plastic rolled goods must be free from pinholes, pitting or dimpling. The material mus

3、t be capable of being routinely handled in the manufacturing process without damage. 1.1.1 Supported PRG (Artificial Leather). The material shall consist of a synthetic resin skin such as Polyvinyl Chloride (PVC), Thermoplastic Olefin (TPO) or Polyurethane (PUR), supported by a textile fabric. The m

4、aterial may also include a laminated foam or foam/scrim back-layer. These materials are typically processed by cut and sew, wrapping, and low pressure molding. 1.1.2 Unsupported PRG (Foil, Compact Sheet). The material shall consist of a synthetic resin skin such as PVC, TPO, or PUR, with no fabric b

5、acking, but may include a foam back-layer (bilaminate), or a foam/skin back-layer (trilaminate). These materials are typically processed by methods such as vacuum thermoforming and low pressure molding. 1.2 Symbols. The finish symbol code defines the material construction and will be assigned by the

6、 responsible department. Trim materials are described by finish symbols which define the commodity, construction code, backings, gloss, grain, and color. The construction code is a unique identifier of the technology used to make a particular product. The construction code is described in detail on

7、the appropriate completed Supported, Unsupported, or Laminated Construction Specification data sheet.
