Name: Rubber O-ring Size: wire diameter * inner diameter Material: NBR, FKM, HNBR, Silicone, custom material Color: Black, brown, green, yellow, red, white, custom color Brand: HTOB Country of origin: Hebei, China Fluorocarbon (FKM) has excellent resistance to high temperatures, ozone, oxygen, mineral oil, synthetic hydraulic fluids, fuels, aromatics and many organic solvents and chemicals. Low temperature resistance is normally not favorable and for static applications is limited to approximately -26°C (-15°F) although certain compounds are suitable down to -46°C (-50°F). Under dynamic conditions, the lowest service temperature is between -15°C and -18°C (5°F and 0°F). Gas permeability is very low and similar to that of butyl rubber. Special FKM compounds exhibit an improved resistance to acids and fuels.  O-ring applications can be very demanding.  GFS Engineers are available to consult on any O-ring application.  Click here to contact a GFS Engineer.

End caps are designed for applications where the shaft does not pass through the housing wall of the bore. The end cover provides protection for the bearings. The covers are designed to fit into housing bores for rotary shaft seals. They have the same tolerances as those for the O.D. of a seal. The inner housing is carbon steel and the outer seal is nitrile rubber. It is mainly used for the orifice, the core opening and the bearing of an oil seal, which is particularly used as a substitute for an end flange or an end cover in a gear box, and the rubber layer at the outer diameter ensures the oil leakage in the oil seal seat.  At the same time,it also strengthens the neatness and beauty of the cabinet. FKM EC CUP END VK OIL SEAL Advantages: 1. good static sealing 2. compensation for different thermal expansion 3. there is no risk of exposure to corrosion 4. effective protection against air side pollution 5. allows higher surface roughness of steel holes 6. installed in the split groove https://www.htoboilseal.com/products/fkm , -ec-cup-end-vk-oil-seal.html

The application of wax micronized powder in road marking is mainly used as a functional additive to improve the performance of marking coatings. The following are its specific uses and advantages: 1. Anti-fouling and anti-adhesion Anti-adhesion: wax micropowder (such as polyethylene wax, Fischer-Tropsch wax, etc.) added to hot melt road marking coatings can form a fine wax layer on the surface of the coatings, reduce the adhesion of dust and oil, and reduce the wear and tear of vehicle tires on the markings. Anti-pollution: especially in rainy and snowy weather, the hydrophobicity of wax can delay the penetration of pollutants and keep the reflectivity of the marking line. 2. Abrasion resistance and durability Wax micropowder can enhance the hardness and abrasion resistance of the paint, reduce the wear and tear caused by long-term vehicle crushing, and extend the life of the marking line. Synergize with resin, glass beads and other ingredients to enhance mechanical strength. 3. Optimization of construction performance Fluidity and dispersion: Wax micropowder can improve the fluidity of the paint in the high temperature molten state, making the construction smoother and the marking line more level. Anti-settling: Prevent fillers (such as titanium dioxide, glass beads) in the paint from settling when stored, and maintain uniformity. 4. Reflective performance aid The wax layer on the surface can protect the reflective glass beads from falling off easily and maintain the reflective effect at night. 5. Environmental protection and cost Part of the wax micropowder (such as vegetable-based wax) can replace petroleum-derived components, reducing the burden on the environment. Reduce the cost of frequent maintenance of marking.

Glycine is a non-essential amino acid that is widely present in the human body and participates in protein synthesis, metabolic regulation and various physiological functions. Its core functions include regulating neurotransmitters, antioxidation, promoting collagen production, assisting detoxification and improving sleep quality, etc. It is widely used in the medical, health care products and food industries. Top Quality Glycine 80Mesh Advantages: Sweetness and low calories: Glycine has a sweetness of 70% that of sucrose, but its calorie content is only 1.96 kcal/g, making it suitable for low-sugar food applications. Water solubility and stability: Glycine is highly soluble in water, resistant to high temperatures and acids and alkalis, and suitable for various processing conditions. Versatility: Glycine has the properties of flavoring, preservative, buffering and antioxidant. Metabolic regulation: Glycine is involved in protein synthesis, detoxification and collagen production. Antioxidation: Glycine inhibits lipid oxidation and extends the shelf life of food.

Calcium L-aspartate is a white powder, odorless, hygroscopic, readily soluble in water, slightly soluble in organic solvents, and its aqueous solution is neutral. Calcium L-aspartate is stable in high-temperature or neutral/alkaline environments and is suitable for various processing conditions. Advantages: High absorption rate:  Calcium L-aspartate chelating structure promotes the efficient absorption of calcium ions in the small intestine (superior to calcium carbonate, calcium phosphate, etc.). Mild and non-irritating: Calcium L-aspartate has little irritation to the gastrointestinal tract and is suitable for people with insufficient gastric acid secretion (such as the elderly). Synergistic nutrition: Calcium L-aspartate provides calcium while supplementing aspartic acid (participating in energy metabolism and immune regulation).

Sodium diacetate (SDA) is one of the most excellent new varieties for mold prevention and preservation in grain, food, and feed additives. It has high efficiency in mold prevention, preservation, and increasing nutritional value. It is suitable for safe storage of grain seeds, as well as for mold prevention and preservation of feed, increasing nutritional value, and improving palatability. It is especially suitable for the preservation of corn and grains, and its effect is better than that of calcium propionate. The addition amount is only half of calcium propionate, but the price is lower than that of calcium propionate. Advantage Security Food Grade Sodium Diacetate has low toxicity, with an allowable daily intake (ADI) of 0-15mg/kg per person. Sodium diacetate's final metabolites in the body are carbon dioxide and water, with no residue and no toxic side effects Nutritional value Sodium diacetate is used for the preservation of forage silage, which can improve the utilization rate of protein in forage.
