The sealant used on easy open end cans is used to fill the configuration gap, to play a sealing effect of adhesive. It has the functions of leakage, waterproof, anti-vibration and sound insulation and insulation. The main components of sealant are as following.
1. Elastomer. Sealant is based on rubber which is a kind of elastomer or polymer, elastic and compression properties. Rubber provides flexibility, strength, and chemical resistance to cans. However, only this kind of rubber itself is unable to obtain all the physical properties of the sealant can lid, so it requires a variety of additives and preparation of additives.
2. Mineral filler. The most important additives are mineral fillers, such as calcium carbonate and kaolin. The role of fillers include strengthening the polymer, regulating the viscosity of the liquid, and controlling the cost without affecting the physical properties of the material.
3. Cohesive resin. Natural and synthetic resins are also important in sealants. They are low molecular weight polymers that function as plasticizers for rubber, which can improve viscosity and adhesion, enhance water resistance, and help to control the rheological properties of liquid and solid rubber films.
