Specific application and effect of triisooctanoate butyltin in automotive interior parts

In the production process of automotive interior parts, butyltin triisooctanoate is widely used, especially in improving product performance and visual effects. The following will introduce in detail the specific application cases of triisobutyltin triisooctanoate in several common automotive interior parts and their significant effects.

Seat material

Seaters are the parts of the interior of the car that directly contact passengers, so their materials are extremely demanding. Although traditional seat materials such as PVC (polyvinyl chloride) are relatively low in cost, they are prone to hardening and cracking in high temperature environments, affecting riding comfort. By adding butyltin triisooctanoate, the flexibility and heat resistance of PVC materials can be significantly improved. For example, in the production of seats of an internationally renowned automobile brand, after adding an appropriate amount of butyltin triisooctanoate, the tensile strength of PVC material has been increased by about 20%, and the hardness has been reduced by about 15%, making the seat surface softer and Not easy to deform. In addition, butyltin triisooctanoate also has excellent light stability, which can effectively prevent the seat from fading or aging due to long-term exposure to sunlight, thereby extending the service life of the seat.

Interior panel coating

Automatic interior panels are usually made of ABS (acrylonitrile-butadiene-styrene copolymer) or PC/ABS (polycarbonate/acrylonitrile-butadiene-styrene alloy) materials, but these materials are During the spraying process, problems such as sag or orange peel are prone to occur. To solve this problem, many manufacturers will add butyltin triisooctanoate as a catalyst and stabilizer to the coating formulation. It not only speeds up the curing speed of the coating, but also significantly improves the smoothness and flatness of the coating surface. For example, after a high-end brand of cars introduced triisooctanoate butyltin in the interior panel coating process, it was found that the uniformity of the coating thickness was increased by 30%, and the gloss reached more than 95GU (GU is a gloss unit), far exceeding the industry standard . More importantly, long-term testing has shown that this coating has extremely strong scratch resistance and pollution resistance, and will not lose its original bright appearance even in the face of frequent cleaning.

Sealing strip

Auto seal strips are mainly used in the gaps in the car body, which plays a role in sound insulation, waterproofing and dustproofing. Due to the bad working environmentIn addition, the sealing strip must have good elasticity, weather resistance and compression-resistant permanent deformation. Traditional rubber sealing strips may lose their original shape or even break under extreme temperature conditions, while EPDM (EPDM) modified by adding butyltin triisooctanoate exhibits better comprehensive performance. For example, a joint venture brand car used an EPDM formula containing butyltin triisooctanoate in the production of seal strips. The results showed that its compression permanent deformation rate was only below 5% (national standard is ≤20%), and the low-temperature brittle temperature dropped to – Below 45℃, it fully meets the strict requirements for winter use in cold northern areas. In addition, butyltin triisooctanoate can also inhibit the occurrence of side reactions of vulcanization inside the sealing strip and further improve product quality stability.

Surface treatment agent

In order to improve the overall texture of automotive interior parts, many manufacturers will use special surface treatment agents to modify parts. Such treatment agents usually contain a variety of functional additives, of which butyltin triisooctanoate is an indispensable member. It not only acts as a coupling agent to promote bonding between different materials, but also adjusts the viscosity of the treatment agent to suit different construction conditions. For example, during the surface treatment of a domestic brand car, technicians found that after adding an appropriate amount of butyltin triisooctanoate, the adhesion of the treatment agent was nearly doubled, and the surface showed a delicate matte effect, which not only avoided The reflection interferes with the driver’s vision and adds a sense of high-end. In addition, the treatment agent also exhibits strong chemical corrosion resistance and is not easily damaged even if it is exposed to oil stains or cleaning agents for a long time.

In order to more intuitively demonstrate the effect of butyltin triisooctanoate in actual applications, the following is a comparison table of some experimental data:

Project	Butyltin triisooctanoate was not added	Add butyltin triisooctanoate	Elevation
Tenable strength of PVC seat material	15 MPa	18 MPa	+20%
PVC seat material hardness	75 Shore A	64 Shore A	-15%
Interior panel coating gloss	70 GU	95 GU	+36%
EPDM seal strip compression deformation rate	12%	5%	-58%
Surface treatment agent adhesion	3 N/mm²	6 N/mm²	+100%

From the above data, it can be seen that the addition of butyltin triisooctanoate can indeed significantly improve the performance indicators of automotive interior parts, and has achieved a qualitative leap in both mechanical strength, appearance effect and durability.
