The TSK6712G standard, developed by Toyota vehicle company, describes the requirements for sealing foams used in vehicle interior coatings. The foam sealant is mainly used to insulate the inner duct related parts of automobiles.
Design flexibility is crucial in automotive assembly and fastening applications. Increased use of plastics and the growing need to bond dissimilar materials present a variety of bonding challenges that may demand pressure-sensitive adhesives. With conditions ranging from extreme temperatures and the presence of oils and chemicals to low surface energy materials and stringent requirements, adhesive selection for these applications can be challenging. However, these adhesives must also be tested to ensure compliance with the Toyota TSK6712G standard.
Specially designed for many unique product requirements today, polyurethane foams are used in a wide variety of applications throughout the vehicle. The most common areas of application are: reticulated polyether or polyester for air filters, low permeability ethers for air/dust sealing, acoustic foams for sound absorption, polyether/polyester for low volatile organic compounds for indoor applications, and high density for comfort or safety pads / hard polyether.
Along with the Toyota TSK6712G standard, other standards referenced in sealing foam tests are: Ford WSS-M99P48, GM GMW16750, Hyundai / Kia MS257-06 and MS300-55 and Daimler DBL 5450.
In general, sealing foam requirements can be listed as follows: superior shock absorption with closed cell foam, high sealing performance and workability with a flexible and rigid material, improved performance with high tear and elongation strength, high chemical resistance of polyolefin resin and improved sound with closed cell foam. versatility.
Meanwhile, almost all car manufacturers use low-emission polyurethane foam seals that meet strict limit requirements. VOC concentration limit values in vehicles are well below those accepted in buildings.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides testing services for sealing foams used in interior coatings, within the scope of Toyota TSK6712G standard, with its trained and expert staff and advanced technological equipment.
