1. Paste sealant: used for static joints, with a service life of 2 years or more, and materials include oil and resin, polybutylene, and asphalt.

2. Liquid elastomer sealant: formed by vulcanization of liquid polymer to form an elastic state, which can withstand repeated joint deformation. Commonly used materials include liquid polysulfide rubber, thiol-terminated polypropylene ether, liquid polyurethane, room temperature vulcanized silicone rubber, and low molecular weight butyl rubber, usually two-component.

3. Hot melt sealant: mixed with elastomer and thermoplastic resin, extruded after heating (150-200°C), and formed after cooling. Materials include isobutylene polymers, EPDM rubber, thermoplastic styrene block copolymers, blended with EVA, EEA, polyethylene, polyamide, polyester, etc.

4. Liquid sealant: used for mechanical joints to replace solid gaskets. The material is polymer rubber or resin, which is divided into non-drying adhesive type, semi-drying viscoelastic, dry adhesion type, and dry peelable type.
