Silicone vs EPDM: Selecting the Right Elastomer for High-Temperature Seals
Compares silicone and EPDM across thermal stability, weathering and fluid compatibility — silicone −60 to +220 °C, EPDM −40 to +140 °C — and the trade-off that decides most specifications: EPDM resists ozone and weather, silicone survives the higher temperature, and neither tolerates mineral oil.

FKM vs NBR: Which Rubber Is Right for Your Application?
Compares fluorocarbon and nitrile across temperature, chemical resistance and cost-in-use — FKM −20 to +250 °C, NBR −30 to +120 °C. FKM is the answer where temperature or aggressive media demand it; NBR is the answer everywhere else, and it costs a fraction as much.

Gasket Material Selection Guide
Sets out a decision framework across the compounds we mix — FKM, NBR, EPDM, silicone and neoprene — with temperature ranges, hardness bands and chemical compatibility, and the flange standards a gasket is drawn to: ASME B16.21 for nonmetallic flat gaskets, EN 1514-1, AWWA C111/A21.11 for water.

O-Ring Size Chart: AS568, ISO 3601-1 and BS 1806 Explained
Cross-references the international sizing standards with tolerance and groove-dimension guidance. ISO 3601-1 is the current standard and its size code matches the AS568 dash number; BS 1806 was superseded by BS ISO 3601 but is still widely quoted, so a working chart has to carry all three.

Rubber-to-Metal Bonded Parts: Design & Specification Guide
Covers bond geometry, surface preparation and the failure modes that decide whether a bonded part lasts — across the five applications where the bond is the part. No load-rating table: a load rating belongs to a part, not to a bond. We bond in-house — bushes, mounts and bonded seals — so the guide is written from the tooling and the process rather than from a textbook.

How to Evaluate a Precision Rubber Manufacturer: 8 Questions to Ask
Sets out a due-diligence checklist for quality systems, tooling ownership, capacity and documentation — including the three structural questions that separate a manufacturer from a trading house: who mixes the compound, who owns the tooling, and whose name is on the batch record.

Sponge & Foam Rubber Datasheet
Service temperatures, ASTM D1056 designations, density and compression force deflection for the five cellular compounds we mix — EPDM, neoprene, NBR, natural rubber and silicone. Cellular figures differ from the same polymers in solid form; section 03 explains why. No form, no email address required.
