Polyolefin Hot Melt Glue Granule for Car A/C Filter 4-Sided Edge Bonding , 7mm White Hot Melt Adhesive
TF1151 Polyolefin Hot Melt Adhesive for Automotive Filter 4-Side Edge Bonding
In automotive filter manufacturing, weak edge bonding, unstable line speed, and adhesive contamination can directly affect product quality and audit approval. TF1151 modified PO hot melt adhesive is developed to solve these challenges in 4-side edge sealing of cabin and A/C filters.
Built on advanced polyolefin hot melt adhesive technology, TF1151 delivers reliable bonding performance, stable processing behavior, and international regulatory compliance—making it ideal for manufacturers supplying the global automotive market.
Stronger Bonds for Demanding Automotive Conditions
TF1151 is formulated with modified polyolefin resins that provide significantly higher bond strength than standard PO adhesives. It effectively bonds filter media to edge frames and bands, including PP, PE, and non-woven materials. The cured bond resists separation under temperature fluctuations, vibration, and humidity, ensuring long-term durability inside vehicle environments.
The adhesive is designed for direct use on standard 4-side edge bonding equipment, allowing manufacturers to improve bonding performance without changing machine configurations.
Stable Processing That Matches Line Speed
Production efficiency depends on timing and temperature control. TF1151 is engineered to integrate smoothly into existing processes:
Controlled Open Time (8–15 seconds)
Supports continuous 4-side edge bonding without premature setting or bonding delay
Flexible Temperature Settings
Box Temperature: 170–200°C
Tube/Gun Body Temperature: 160–190°C
Compatible with common heating systems used in automotive filter production lines
Low-Contamination Formula
Clean white granules help prevent carbonization, dark specks, or edge staining, reducing quality inspection workload
Designed for Global Automotive Supply Chains
TF1151 complies with major international chemical and environmental regulations, including REACH, RoHS, TSCA, and CE. Its performance has been validated for use in automotive cabin and air conditioning filters across passenger vehicles, commercial fleets, and electric vehicles. This helps suppliers meet OEM quality expectations and global market entry requirements.
Practical Handling and Sustainable Packaging
Supplied in 25 kg moisture-protective, resealable bags, TF1151 maintains stable quality during storage and handling. The packaging supports easy hopper feeding and minimizes waste. The adhesive formulation also aligns with global environmental and recycling standards, supporting sustainable production initiatives.
