3D expansion rubber block
SnugBaffle102 is made of EVA as the base material and has sound insulation and noise reduction functions, sealing and soundproofing the gaps between car body sheet metal.
Product features
Used for blocking air flow and noise in the circular circuit formed by the front (A-pillar), middle (B-pillar), rear (C-pillar), and rear door (D-pillar) pillars of the door threshold, ensuring the effectiveness of the vehicle's bypass sealing.

- The welding workshop can directly insert the process holes on the corresponding sheet metal of the product's buckle into the installation, making installation convenient.
The colors of the expansion film are: yellow, blue, black, and gray.
Packaging in cardboard boxes or turnover boxes or according to customer requirements.
1. Logistics transportation requires that the transportation process: ① avoid high temperatures (below 55 ℃); ② Avoid direct sunlight and exposure to direct sunlight;
2. Standard storage environment, product standard storage environment required: ① Storage temperature range: -5 ℃~30 ℃; ② Storage humidity range: 30%~80%; ③ Other conditions: Avoid direct sunlight, stay away from heat sources, and place in a cool and dry place;
3. Shelf life: Under standard storage environment, the shelf life is 6 months; The product exhibits performance degradation after being stored in an environment exceeding the standard (temperature of 40-65 ℃, or humidity greater than 80%) for a total of 7 days and cannot be used again.
