Rubber Buffers / Bumpers
Buffers / Bumpers
Since the rubber buffers are built of a cost effective basic material, our Programme offers an economic solution for most technical requirements. The energy absorption of rubber buffers is limited due to their incompressible material.

Oil and natural gas are the basic materials for synthetic caoutchouc. For many years this has been a substitute material for natural caoutchouc, but today synthetic caoutchouc is used increasingly as the first choice for many applications. Today, there is a wide range of synthetic caoutchoucs, whose properties allow a variety of applications, thereby establishing the use of rubber technology within modern methods.
Moreover, rubber is not merely a chemical substance, but a compound of many different materials. The varied mechanical and anti-corrosive properties can only be achieved by a recipe of several hundred substances. Caoutchouc as a macromolecular material provides the elastic components of the rubber. The mechanical properties, such as breaking elongation, resilience elasticity, strength and continuous breaking strength are dependent on it. The addition of chemicals and other additives and the subsequent vulcanization process make the material useful.
The multitude of additive combinations as well as the many physical forms means that for most problems there is a solution.
FAQs
Frequently asked questions
What limitations does natural rubber have in terms of chemical resistance?
Natural caoutchouc rubbers are characterised by their very high elasticity and tensile strength. Other qualities are their notch impact resistance and good abrasive resistance. Among all Elastomers these have the highest mechanical and dynamic load capacities. Natural caoutchouc is not resistant to electrolytic liquids, aliphatic, aromatic and chlorinated hydrocarbons.
What makes rubber buffers unsuitable?
Standard quality rubber buffers are not suitable for low temperature applications or for exposure to mineral oils or gasoline. When exposed to mineral oils, buffers made from NBR, CR or our S-quality buffers must be used.
What does underdelivery and overdelivery of made-to-order rubber buffers mean?
The vulcanization process produces a significant amount of discard, thus fluctuations in quantities occur during production. Remanufacturing often proves to be more expensive than the original batch ordered, hence conditional under- or overdeliveries of up to 10% are acceptable sales standard in the rubber industry.
