Often going unnoticed, door bumpers are important at work and in your home to protect your walls from dings and dents caused by doorknobs. Today, we’re talking about the features our door bumpers have that make them stand out from the competition.
- Material Compound: These bumpers are made with 35 Durometer Shore A grade elastomer. It also features a fastener chemically bonded to the SBR elastomer for easy attachment to equipment.
- Impact Resistance: The impact or shock resistance of an elastomer is determined by striking a sample with a swinging pendulum (hammer). The sample is placed at the lowest point of the arc traveled by the pendulum head. Measuring the difference in the distance of the upswing of the pendulum after the impact, compared to the same upswing with nothing in its path, determines the energy in breaking the sample which is the measure of impact strength.
- Non-marking Grey Color: The material and its impact resistance keep the bumper from making any marks on the door or wall, and its grey color keeps it hidden from view.
These elastomer hoses are used for marine, recreation vehicle and automobile engine exhaust and can be custom-made when there is limited space in an engine.
When subjected to load, all elastomers exhibit an increasing deformation with time, know as creep. This occurs at any stress level and takes place in compression, tension and shear loadings and varies for each type of loading. In service, creep can be minimized by using low working stresses and avoiding high temperatures. No rapid method has been developed for its measurement because there is no know way of accelerating time effects without introducing inaccuracies in predicting rate of creep. Continue reading
Cast polyurethane, formulated to have a balance of characteristics associated with premium materials, is a great solution in demanding roller applications. In addition to its superior material characteristics, urethane can be molded and finished easily.
• Superior abrasion resistance
In applications, such as manufacturing diapers, forming food product bags, or cash counting systems, urethane offers the abrasion resistance necessary to reduce wear, thereby reducing the frequency of worn roller replacement. Continue reading
