Description
The scrim protects the edge from tearing when the blank is repositioned and serves as a barrier for adhesive during lamination. It also holds the three-dimensional shape, so die-cutting comes out cleaner and there is less scrap. According to the manufacturer, the composite exceeds existing materials in durability, recovers fully (100 %) after indentation and can be tuned in stiffness for a specific part. It is specified by Ford WSS-M8P18-B3 and the methods ASTM D3574 A, D, E and F. Tensile strength is at least 75 psi (517 kPa), elongation at least 135 %, tear resistance 1.30–2.50 lbf/in (228–437 N/m), and compression set after 50 % compression no more than 12 %. Flammability complies with ISO 3795 and SAE J369 for interior materials. It is made at the Santa Teresa plant in New Mexico. The polyurethane base reduces part weight, and thicker versions add savings while keeping air exchange.
How to choose
The material is selected for a specific part, so first determine the required stiffness and feel to the touch. For a front panel that is often loaded, look at compression set of no more than 12 % and recovery. For parts where weight matters, take thicker versions. For interior repair, the underlayer for your fabric or film is best agreed against Ford specification WSS-M8P18-B3.

FAQ
What is the density of the Trim Craft composite?
From 3.8 to 4.2 lb/ft³, that is 60–67 kg/m³, per ASTM D3574 A.
What function does the scrim perform in this composite?
It protects the edge from tearing during repositioning, blocks adhesive during lamination and preserves the three-dimensional stability of the blank.
What tensile strength and elongation are specified?
Tensile strength at least 75 psi (517 kPa), elongation at least 135 %. Both parameters are determined per ASTM D3574 E.
Does the composite meet interior flammability requirements?
Yes, flammability complies with ISO 3795 and SAE J369. The material specification is Ford WSS-M8P18-B3.
How is Trim Craft better than spacer fabrics?
According to the manufacturer, it is more durable, recovers fully (100 %) after indentation, is lighter and can be tuned to the part.
