Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of polysulfide sealant, it is recommended to prioritize confirming key technical parameters such as tensile strength, elongation at break, and medium resistance of the product to ensure its suitability for specific engineering environments.
  • Polysulfide sealant is commonly used in scenarios such as building joints, airport runways, or underground pipe galleries. When purchasing, different curing speeds and flexibility models should be selected according to the application environment.
  • When selecting suppliers, priority can be given to indicators such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support to evaluate their supply stability.
  • When using polysulfide sealant in the industrial anti-corrosion field, attention should be paid to its acid and alkali resistance and long-term durability parameters to avoid sealing failure due to insufficient material properties.

Knowledge Base

Q

Polysulfide sealant is a sealing adhesive made mainly of liquid polysulfide rubber, combined with thickening resin, vulcanizing agent, accelerator, reinforcing agent, etc. This type of sealant has excellent resistance to fuel, hydraulic oil, water, and various chemicals, as well as heat and atmospheric aging. It can be divided into two component (or three component) and one component types according to its composition.

Q

Low modulus polysulfide sealant is a high-performance building sealing material, and its brief introduction is as follows: Composition and characteristics of low modulus polysulfide sealant The main components of low modulus polysulfide sealant are formulated with polysulfide rubber as the main base material and various additives such as vulcanizing agents, fillers, etc. added in appropriate amounts. Characteristics of low modulus polysulfide sealant Low modulus polysulfide sealant Low modulus: has a lower
