H.M. Royal: Reliable Sulfur Suppliers

Because sulfur is such a versatile, abundant and well-known element, it’s used in a vast range of applications and industries. From rubber compounding and adhesives to cement, glass and fertilizers, sulfur’s many forms make it an ideal element and vital component in many compounds.

Rubber Maker’s Sulfur

Sulfur is a key element in rubber compounding. Rubber Maker’s Sulfur is a critical additive in rubber compounds and facilitates the vulcanization process of rubber.

When used as a rubber additive, sulfur has the ability to retain vital characteristics, such as tensile strength, elongation, and hardness, without dissolving into the mixture.

Specifically, in soft or elastic rubber compounds, Rubber Maker’s Sulfur can often be a small but impactful ingredient needed to create the desired product. When considering semi-hard rubber and ebonite, vulcanizing sulfur makes all the difference in a usable end product.
