MALEIC HYDRAZIDE Resistant O-Rings and Seals

Maleic hydrazide, also known as 1,2-dihydro-5-methyl-4H-pyrazol-4-one, is an organic compound used as a herbicide and fungicide. It is used in agriculture to control grasses and broadleaf weeds, as well as to protect crops from fungal diseases.

Common types of failures when rubber is exposed to maleic hydrazide include cracking, embrittlement, swelling, and discoloration. Maleic hydrazide can cause rubber to swell and crack, leading to softening and other deformations. Additionally, maleic hydrazide can cause rubber to become brittle, leading to a decrease in its elasticity and strength. Maleic hydrazide can also cause rubber to discolor due to its oxidizing properties. Finally, maleic hydrazide can cause rubber to become more susceptible to other environmental factors, such as ozone and ultraviolet radiation, resulting in accelerated aging.


Fluorosilicone (FVMQ, FSIL)

Fluorosilicone o-rings are a hybrid of silicone and FKM resulting in great jet fuel resistance with high and low temperature performance. Also widely used in semiconductor Ashing equipment with strong resistance to oxygen plasma, FVMQ fluorosilicone o-rings also feature excellent flexibility, compression resistance, aging and sunlight resistance, and overall wide range of basic chemical resistance.
