Benefits of Urethane

Polyurethane is one of the most versatile materials in use by all industries. Custom Cast Urethane has proven useful in countless applications and has many advantages over plastics, rubber and metal.

What is durometer?

Durometer is the hardness of a non-metallic product or the gauge used to measure the hardness. The two most common elastomer durometer scales, using slightly different measurement systems, are the ASTM D2240 Type A and Type D scales. The A scale is for softer urethanes, while the D scale is for harder ones.

	SHORE A	SHORE D
		70-80	Safety Hard Hat
		60-70	Shopping Cart Wheel
Hard Urethane Hammers	90-95	40-50
Shopping Cart Wheels	80-90
Car Tires	70-80
Pencil Eraser	60-70
Rubber Band	20-40

Polyester vs. Polyether

Polyester: A chemical building block that provides good resistance to solvents as well as excellent physical properties when it comes to tear and strength and better resistance to abrasion and oil.

Polyether: A chemical building block sometimes used in place of polyester that provides exceptional dynamic properties (lower hysteresis) and better water resistance (resists hydroxylation)

MDI vs. TDI

Methylene Di-isocyanate is used in the production of polyurethanes as a base form of urethane resin.

Toluene Di-isocyanate is used in the production of polyurethanes as a base form of urethane resin with moca curatives.
