Durometer vs. Modulus

Durometer vs. Modulus for Rubber Products

Rob Pruyn Other

Durometer is a measure of a rubber’s resistance to indentation. More commonly, however, it’s known as a measure of hardness. Modulus, another material property, is the stress or force that’s required to produce a strain. Higher-durometer rubber usually has a higher modulus, but that doesn’t mean the relationship between durometer and modulus is straightforward – especially in terms of stiffness. …

FTIR Spectrometer with Microscope Identifies Materials, Solves Challenges

Rob Pruyn Products and Services

The Rubber Group is announcing its acquisition of an FTIR spectrometer and microscope that the rubber molding company will use to identify compounds and analyze specific areas of interest. FTIR, an acronym for Fourier-transform infrared spectroscopy, supports the reverse engineering of rubber materials where the elastomer is unknown. FTIR spectroscopy and microscopy applications include the verification of rubber compounds and …

The Rubber Group Reduces Lead Times by Increasing Low-Tonnage Capacity for Injection Molded Products

Rob Pruyn Products and Services

The Rubber Group is announcing its acquisition of an injection molding machine that will reduce lead times by increasing capacity for products that require lower-tonnage injection. The new equipment, a REP G10 vertical injection molding machine, will also increase process control for precision products while supporting material and color changeovers that are both faster and cheaper. Additional benefits include energy …

Ultra-Low Temperature FKM

Rob Pruyn Products and Services

Ultra-low temperature FKM is used in molded rubber products that need to withstand cold temperatures and aggressive chemicals such as those found in automotive, oil and gas, and aerospace applications. This fluoroelastomer provides reliable sealing at service temperatures ranging from -40° to 150° C and offers strong fluid resistance. Ultra-low temperature FKM can replace fluorosilicone in some applications and combines …
