Substrate rigid plastics

When impact resistance and/or strength is required, it can be improved dramatically by the rubber sandwich technique. In this case, a rubber sheet bonded between the rigid plastic or metal substrates will absorb all peel and impact forces. It is also useful in absorbing stresses when thermal expansion and contraction occur.

In the case of rigid plastics, the greatest problems are in reinforced plastics, which are often anisotropic, having directional strength properties. Joints made from such substrates should be designed to stress both the adhesive and the adherend in the direction of greatest strength. Laminates should be stressed parallel to the laminations to prevent delamination of the substrate. ... 

Plastic substrates constitute another variation of the single-lap shear test. ASTM D3163-73 addresses the lap shear testing of rigid plastics. This test is important because plastics are becoming more useful in structural applications involving adhesives instead of mechanical fasteners. 

There is increasing use of rigid plastics as substrates in place of metals. Plastic surfaces may be prepared by chemical cleaning and/or surface roughening with a mechanical blast. Flame treatment and corona treatment are also viable options. 

Contact adhesives are used to manufacture furniture and countertops of high pressure plastic and particle board, movable and permanent office partitions, assemblies of cold rolled steel to honeycomb cardboard, and foamed substrates for both steel doors and prefabricated curtain walls. Other applications for contact adhesives include small product assembly such as toys, sporting goods (with substrates such as leather), aluminum foil, plastic films, rigid plastic and foams.

Compaction of the filter bed over time will result in gas channeling and pressure-drop increases. This can be avoided by adding large, rigid particles such as plastic spheres, ceramics, or wood/bark chips to provide additional support to the filter substrate. 

Textiles, paper, and other flexible substrates such as fusible interlining, interlinking drapery and upholstered fabric, and carpets are examples of large volume applications. Another important market is with metals and other rigid materials. Included are plastics (pipes, tanks, screens, etc.) that can provide protective coatings using its variety of processing techniques.
