Blog → We decided to buy polyurethane bushings. What to ask the manufacturer?

Decided to switch to polyurethane, but lost among the offers? In Ukraine, it is possible to manufacture parts to order at an affordable price, and there is already plenty to choose from. To get a quality product, contact the manufacturer, not an intermediary.

But how do you choose your supplier? Ask him the following questions:

• What type of polyurethane does he use for the production of silent blocks?
• How accurate is the part ordered as a copy of the original?
• How firmly are the outer cage, polyurethane insert and metal sleeve bonded together?
• What guarantees does the manufacturer give and under what conditions?
• When will the spare part be produced?

Polyurethane silent blocks from PoliPro

The PoliPro company uses 4-component hot curing cast polyurethane in the manufacture of polyurethane silent blocks. For 5 years of work, we have tested materials from different manufacturers and settled on this, because it is this material that allows us to produce strong and wear-resistant parts that work stably in the temperature range from -20⁰С to +40⁰С, although its operating temperature range is even wider.

Our company produces exact copies of the original silent blocks for all brands of cars, both with and without an outer clip. We do not agree to experiment with making changes to the design of original parts, because we trust the engineering thought of the automaker, preserving their design and characteristics so that you enjoy the flawless operation of your car.

The functionality of the silent block depends on the reliability of the connection of its parts: the outer cage, the polyurethane insert and the metal sleeve. In order to achieve a monolithic construction, we degrease the metal parts by sandblasting and use a special primer to bond them with polyurethane. Such a connection turns out to be surprisingly tear-resistant: under extremely high loads, the polyurethane itself is damaged, but not the place of its connection with metal parts.

Thanks to all these points, we are confident in the quality of PolyPro polyurethane silent blocks and their ability to withstand high loads. Therefore, we provide a written guarantee for a period of 1 year without mileage *.

Our production of polyurethane silent blocks works seven days a week and holidays, so we are ready to send you spare parts within 3 days from the date of order. Call or write to us to evaluate the benefits of cooperation with "PolyPro".

* The warranty does not apply in case of violation of the operating conditions of products made of polyurethane, for example, when welding a silent block with a lever, due to which the material is destroyed due to high temperatures.
