Strip brushes are made from a variety of materials, each chosen for specific properties that suit different applications. The main components of a strip brush are the filament, the backing, and the channel.
1. **Filament Materials:**
- **Nylon:** Known for its flexibility, durability, and resistance to abrasion and chemicals. It is suitable for both wet and dry applications.
- **Polypropylene:** Offers good chemical resistance and is less expensive than nylon. It is often used in wet environments.
- **Horsehair:** A natural fiber that is gentle and used for delicate cleaning tasks.
- **Tampico:** A natural fiber derived from the agave plant, known for its water retention and heat resistance.
- **Wire (Steel, Stainless Steel, Brass, Bronze):** Used for heavy-duty applications requiring abrasion and heat resistance. Stainless steel is preferred for its corrosion resistance.
- **Polyester:** Offers good resistance to moisture and chemicals, often used in environments where nylon might absorb too much water.
2. **Backing Materials:**
- **Galvanized Steel:** Provides strength and is cost-effective, but may rust if the coating is damaged.
- **Stainless Steel:** Offers excellent corrosion resistance, ideal for harsh environments.
- **Aluminum:** Lightweight and resistant to corrosion, suitable for applications where weight is a concern.
- **Plastic:** Used for lightweight applications and where metal might cause issues, such as in electrical environments.
3. **Channel Materials:**
- **Steel:** Provides a strong and durable channel for holding the filaments.
- **Aluminum:** Lightweight and corrosion-resistant, often used in applications where weight is a factor.
- **Plastic:** Used for non-conductive applications or where metal channels might corrode.
These materials are selected based on the specific requirements of the application, such as temperature, chemical exposure, and mechanical stress.
