Natural latex:

It is a kind of thick milky white liquid, which looks like milk. It is the emulsion water dispersion of rubber particles in the near neutral medium. Due to the action of oxygen and microorganism in the air, the acidity of the latex increases, and it can naturally coagulate within 2-12h. In order to prevent natural coagulation, a certain amount of ammonia solution needs to be added as a protective agent. Natural rubber latex belongs to the thermoplastic synthetic resin of rubber, which is characterized by high elasticity, good film-forming performance during bonding and flexibility of the film, so that the film has excellent flexure resistance, seismic resistance and creep resistance, which is suitable for the bonding of components under dynamic conditions and the bonding between materials with different thermal expansion coefficient.

Polyurethane material:

It is the abbreviation of polyurethane. Its English name is polyurethane. It is a kind of polymer material. Polyurethane is a new organic polymer material, known as the "fifth largest plastic", which is widely used in many fields of national economy due to its excellent performance. The product application fields involve light industry, chemical industry, electronics, textile, medical treatment, construction, building materials, automobile, national defense, aerospace, aviation, etc.

Polyurethane has many excellent properties, including:

(1) Wide adjustable range and strong adaptability

(2) Good wear resistance;

(3) High mechanical strength;

(4) Good adhesion;

(5) It has good elasticity, excellent resilience and can be used for dynamic joints;

(6) Good flexibility at low temperature;

(7) Good weather resistance, service life up to 15-20 years;

(8) Good oil resistance;

(9) Resistance to biological aging;

(10) The price is moderate.
