Dibutyl thiourea (also known as DBTU) is an organic compound commonly used in the rubber and plastic industries. It is used as a vulcanizing agent to improve the strength, elasticity, and abrasion resistance of rubber products. It is also used as an accelerator in rubber and plastic products to speed up vulcanization.
When exposed to dibutyl thiourea, rubber can become brittle and crack due to the high temperatures generated during vulcanization. Additionally, the chemical can cause rubber to swell, soften, and lose its strength and elasticity. It can also cause rubber to discolor and break down over time, leading to premature failure.
Viton ® o-rings from Marco Rubber offer excellent compatibility with a range of chemicals, oils and resist high temperatures up to 400F. Viton ® is also known as FKM made of fluoroelastomer one of the most versatile and widely used sealing materials.
