The 25mm D-Type Clutch (plastic bracket) is a mechanical structure used to connect and fix the bead chain, which is usually used in scenes such as cars, motorcycles, and industrial equipment. However, when the product is used in the curtain system, whether it has waterproof, dustproof, UV-proof and other characteristics will directly affect its stability and durability in long-term use.

This product is made of ABS material, some of which are ABS 30% glass fiber reinforced. ABS material has good impact resistance and is suitable for use under dynamic loads. ABS material has certain weather resistance under normal conditions, but its UV resistance is weak. Long-term exposure to sunlight may cause material aging, discoloration or strength loss.

ABS has a certain tolerance to general chemicals, but is not resistant to strong acids and alkalis. ABS material has a smooth surface and is easy to clean, but it is not waterproof and is prone to moisture or rust in a humid or vaporous environment (if the bracket has metal parts).

The 25mm D-type clutch itself is not waterproof. Its structure is a plastic bracket without a sealing design, so it is easy to get wet in a humid environment. If the product is designed to be dustproof and waterproof, it may be equipped with a sealing cover or waterproof coating to improve the waterproof performance. In the curtain system, if it is installed outdoors or in an area close to a window, it is recommended to choose a model with a waterproof function to prevent rain penetration or moisture erosion.

The plastic bracket of the 25mm D-type clutch has a simple structure and is not dustproof, which is easy to accumulate dust or enter. If the product is designed to be dustproof (such as a dust-proof clutch in industrial equipment), it may be sealed or coated to reduce dust ingress. In the curtain system, if it is installed in a poorly ventilated or dusty area, it is recommended to choose a model with a dustproof function to extend the service life.

ABS material is not UV-resistant, and long-term exposure to sunlight will cause the material to become brittle, cracked or faded. If the product is designed to be UV-resistant, it may be treated with UV stabilizers or coatings to enhance UV resistance. In the curtain system, if it is installed in an area with direct sunlight, it is recommended to choose a model with UV protection to prevent material aging.

If the curtain system is installed indoors, away from direct sunlight and humidity, the 25mm D-Type Clutch may work fine, but it is recommended to choose a model with dust and moisture resistance. If the curtain system is installed on a balcony, terrace or area near a window, it is recommended to choose a model with waterproof, dustproof and UV protection to ensure long-term use.
