Suspension tuning parts

One of the well-known applications for polyurethane is suspension tuning parts. Polyurethane elastomers based on TDI and MDI are used for the production of bushes, supports, stabilizers and other parts.

Due to the unique physical and mechanical properties of polyurethane elastomers – elasticity, resistance to dynamic and static loads, resistance to abrasion, moisture, engine oil, and ambient temperature changes — suspension parts made of polyurethane serve for a long time, reliably, make it possible to adjust the operation of the suspension for different driving modes.

Despite the fact that a polyurethane product is several times more expensive than a rubber product, this disadvantage is compensated by its durability, increased strength and wear resistance, as well as the unique stability of polyurethane properties throughout the life of the part. In addition, the method of casting polyurethane products does not require the production of expensive molds, which cannot be said about the production of rubber parts.

For example, the service life of rubber joints of a car is from 8 to 12 months. If the suspension is made of polyurethane, the period of operation increases by 5 times. So, at a price equal to the cost of the “original” made of rubber, there is a significant saving on car repairs. If you have to replace the entire structure of the silent block, complete with shock absorber, traction, lever – it is even cheaper to make products from polymer to order.
