Product details

Sponge rubber strips (also known as **seal strips** in the industry) are components made from a combination of elastomeric (rubber) materials and air cells (sponge). The primary purpose of these strips is to fill gaps between two surfaces to prevent the passage of materials, sound, or vibration.

Below is a comprehensive explanation of the types, applications, and features of these strips:

### 1. Structure and Material (What are they made of?)
Depending on the application, these strips are produced from various materials:
- **EPDM:** The most common type for outdoor use; highly resistant to sun, rain, and high temperatures (e.g., around car windows).
- **Neoprene:** Excellent resistance to oils and chemicals.
- **NBR (Nitrile Rubber):** Specifically for environments in contact with oil and fuel.
- **EVA and Polyethylene:** Primarily used in packaging industries and inexpensive shock absorbers.

### 2. Types of Strips by Structure
- **Open Cell Sponge Strips:** Like a dish sponge, air flows through its cells. These strips are mainly used for **sound insulation and vibration absorption** (because they trap air).
- **Closed Cell Sponge Strips:** Air cells are completely sealed. These strips are **waterproof and windproof** and are used for sealing to prevent any liquid or gas from passing through.

### 3. Industrial Applications
These strips are present in almost all industries:
- **Automotive Industry:** Around doors, hoods, and trunks (to prevent wind, water, and ambient noise from entering the cabin).
- **Construction and Architecture:** Around window and door frames, under doors to prevent dust entry and reduce energy consumption (thermal insulation).
- **Home Appliance Industry:** Around refrigerator doors, washing machines, and microwaves to maintain temperature and prevent steam leakage.
- **Electronics Industry:** In laptop and tablet bodies (to prevent internal component vibration and provide shock absorption when the body is closed).

### 4. Key Features (Why do we use them?)
1. **Compression Set:** Their most important feature; meaning when pressure is applied to the strip and it is compressed, it returns to its original shape after the pressure is removed.
2. **Damping:** Absorbing impacts and preventing direct contact between two hard parts (preventing squeaking or breakage).
3. **Insulation:** Preventing heat and cold transfer between internal and external environments.

### 5. Installation Method
These strips are usually supplied in two ways:
- **Self-Adhesive:** One side has an adhesive layer (usually industrial or double-sided adhesive) to quickly stick to the surface.

Payment: in USDT. ASL Market holds the payment until you confirm delivery.
