The formation of each lamella contributes to the consumption of energy and thus to an increase in elongation at break. Polystyrene homo-polymers deform when a force is applied until they break. Styrene-butane co-polymers do not break at this point, but begin to flow, solidify to tensile strength and only break at much higher elongation. [63]: 426
Bottles, pipes, inner insulation (dielectric) of coax cable (see also PTFE), plastic bags, etc. Polypropylene: PP: Resistant to acids and alkalies, High tensile strength: Auto parts, industrial fibers, food containers, liner in bags, dishware and as a wrapping material for textiles and food Polystyrene (thermocole) PS: Thermal insulator.
The ASA mixtures have excellent rutting resistance and moisture damage resistance. The tensile strength ratio of the ASA and asphalt mixture are all larger than 0.8 and therefore satisfy the Superpave specification. The average coefficient of permeability of the ASA mixture is 6–10 times higher than the asphalt mixture in the same air void level.

For example, molding at a high temperature improves the gloss and heat resistance of the product whereas the highest impact resistance and strength are obtained by molding at low temperature. Fibers (usually glass fibers) and additives can be mixed in the resin pellets to make the final product strong and raise the maximum operating temperature ...
The tensile strength of a material quantifies how much elongating stress the material will endure before failure. [50] [51] This is very important in applications that rely upon a polymer's physical strength or durability. For example, a rubber band with a higher tensile strength will hold a greater weight before snapping.
