Buyer guides for rubber raw materials

Short, practical guides for buyers and compounders. Each one starts with a direct answer, then the detail.

Carbon black grades explained: N220, N330, N550, N660, N774

How ASTM carbon black grade numbers work, how N110 to N990 differ in reinforcement and processing, and which grade suits treads, carcass, hoses, profiles and moulded goods.

Rubber accelerators: types, speed and how to choose

A practical guide to sulphur-cure accelerators: thiazoles (MBT, MBTS), sulfenamides (CBS, TBBS), thiurams (TMTD, TMTM), dithiocarbamates (ZDBC, ZDMC) and guanidines (DPG), with scorch safety and typical uses.

FKM vs NBR vs EPDM: which rubber for seals and hoses?

Compare FKM (Viton-type fluoroelastomer), NBR (nitrile) and EPDM on temperature range, oil and fuel resistance, water, steam and ozone resistance, and cost, with a quick selection table.
