How to meet the VOC level requirements of the automotive industry

        A global market-oriented automotive interior component supplier is currently under significant pressure from its core customer – a top international OEM. To ensure brand reputation and user health, this OEM has implemented the most stringent interior air quality standards in the world for all materials within its supply chain. This means that any adhesive provided by the supplier must pass authoritative VOC testing, meet extremely low odor requirements, and maintain excellent interior bonding strength (such as for the roof, door panels, and carpets), as well as long-term aging resistance. Traditional hot melt adhesives, due to the presence of small molecule residues in their raw materials, are prone to becoming sources of VOC and odors, becoming the biggest obstacle for customers to pass the review and obtain orders.

        Facing this industry-wide challenge, we have launched a series of ultra-low VOC content hot melt adhesives specifically designed for automotive environmentally friendly interiors, and provided a systematic solution from the source to the end:

1. Source material strict control: Select and certify suppliers rigorously, and all use hydrogenated, high-molecular-weight polymers and refined distilled adhesion resins, fundamentally eliminating the introduction of harmful small molecule substances such as benzene and aldehydes.

2. Patent purification process: In production, adopt high-temperature high-vacuum evaporation technology, like an efficient “molecular sieve”, which can strongly extract and remove residual monomers and volatiles in the molten state, ensuring the minimization of VOC sources.

3. Full-process quality system: Establish a three-level inspection system from raw materials, semi-finished products to finished products, and each batch of products can be traced.

4. Seamless application: The product maintains ultra-low VOC characteristics while having stable melt viscosity and appropriate open time, perfectly adapting to the existing automated spraying equipment of customers, without the need to change the existing production process.

        This solution has brought immediate value and long-term market competitiveness to the customer. With complete and authoritative compliance certification reports, the supplier successfully defeated competitors and became the exclusive interior component supplier for multiple new energy vehicle platforms of the OEM, with a significant increase in annual order volume. The supplier regards “completely adopting ultra-low VOC environmental-friendly bonding solutions” as its core promotional point, greatly enhancing its brand reputation and trust among consumers who value health and environmental protection.

        If you are currently working on passing the VOC audits of VW, General Motors, Toyota, Geely, BYD, etc., please contact our technical team to obtain exclusive environmental-friendly bonding solutions.
