Full Synthetic Motor Oil
PTFE material is a perfect ingredient in making more reliable oil seals. These materials are used to make oil seals that can resist dry or unlubricated operations. PTFE oil seals, which are also called teflon oil seals, have a thermal strength ranging from -202 degrees Fahrenheit to 392 degrees Fahrenheit and an excellent chemical resistance. Oil seal PTFE is considered as the future of radial shaft seals.
Oil seals are always exposed to a lot of chemicals, both mild and harsh chemicals. The seals react by showing some signs like cracks, blisters, and discoloration especially when the chemical is harsh. This clearly shows that the chemical is not compatible with the seal, which goes as far as affecting its cross-link density (increase or decrease). When the cross-link density increases, the seal material becomes harder, but when it decreases, the seal material becomes softer.
