Vinyl Fabric Types

 

Non-Expanded vinyl

is made of a thin layer of solid vinyl approximately 1/32 to 1/16th inch
thick with a cloth backing. There are certain types of this material which are made of two or
more layers laminated together. The backing may be made of one of several types of cloth: a
tightly woven, linen type cloth, a loosely woven, cheesecloth type material, or a long fibrous
“polyfill” material Non-Expanded vinyl’s will be found in seat upholstery, door panels, trim
panels and consoles.

Expanded vinyl

is a foam-type material, approximately 1/16th to 1/8th inch thick. A
very thin grain pattern is heat formed only on the very surface of the material. There
is no backing on the material, but the underside of the material is smooth as though it
has been poured onto a flat, smooth surface. Expanded vinyl’s will be found
primarily on door panels, trim panels and consoles in automobiles. Expanded vinyl is
extremely heat sensitive, when heat from the curing tool is applied, expanded vinyl
will quickly melt and retract from itself thus making a small hole larger .

Non-Backed

vinyl’s are just as the name implies, no backing what so ever. Non-Backed
vinyl usually contains a lesser amount of plasticizers thus making it less flexible and not as
soft to the touch. It consists of a single layer of vinyl usually glued and heat formed over a
pre formed substrate. This type of vinyl may not be repaired in the conventional manner,
but it is possible to make a permanent, invisible repair . Non-Backed vinyl’s will be found
primarily in automotive applications such as padded dashes, door panels and consoles.
