Plasticizers play an important role in silicone and MS (modified silane) sealants by adjusting the flexibility, flowability, and weather resistance of the sealant, ensuring excellent performance under different environmental conditions.

In silicone sealants, common plasticizers include PDMS (Polydimethylsiloxane) and white oil. These plasticizers help improve the flexibility of the silicone sealant, reduce its hardness, and enhance its high-temperature and weather resistance. Particularly in applications such as construction, electronics, and automotive sealing, the addition of plasticizers improves the long-term stability and lifespan of silicone sealants.

For MS sealants (Modified Silane Sealants), commonly used plasticizers include PPG (Polypropylene Glycol), DINP (Diisononyl Phthalate), DOP (Dioctyl Phthalate), and SVG08 (Synthetic Vegetable Ester). These plasticizers optimize the processing performance and low-temperature flexibility of the sealant while improving its aging resistance and moisture resistance. MS sealants are widely used in window frames, door frames, construction, and automotive sealing, and the choice of plasticizer directly influences the sealant's workability and performance over time.

Therefore, selecting the right plasticizer for different types of sealants not only enhances their physical properties but also ensures the stability and environmental friendliness of the product during use.
