The Safe Protector is a spiral sheath made from polypropylene (PP), polyethylene (PE) or nylon (PA) through a hot - state winding and shaping extrusion process. It is a new - generation product that replaces traditional metal springs for hose protection. Also known as hose Safe Protectors, wire and cable Safe Protectors,  Safe Protectors, etc. 

 Abstract
The Safe Protector, made from polypropylene (PP), polyethylene (PE) or nylon (PA) through a hot - state winding and shaping extrusion process, is a new - generation substitute for traditional metal - spring - based hose protection products. It also goes by aliases like hose Safe Protector, wire and cable Safe Protector, and  Safe Protector.

This spiral - shaped sleeve features good elasticity and stretching force, effectively binding internal products such as hydraulic hoses, wires, and cables. Made from raw materials like PE, PP, or PA in China, it has excellent wear resistance. Additionally, it offers good resistance to high and low temperatures, oil, UV rays, impact, static electricity, and has high tensile strength.

The quality of the  Safe Protector can be identified based on the following reference standards:
1. Appearance: A high - quality sleeve has a smooth and flat surface, free of material shortages, cracks, damage, burrs, blisters, unevenness, impurities, or color variegations. Otherwise, it is of inferior quality.
2. Hardness: The hardness of a qualified sleeve generally ranges from 85 - 90 degrees on the Shore scale. Deviations from this range, either too low (failing to protect and bind internal products) or too high (prone to brittle fracture in low - temperature environments like Northeast China), are not acceptable.
3. High and Low - Temperature Resistance: Place the sleeve at 80°C for 1 hour, room temperature for 0.5 hours, - 40°C for 1 hour, and room temperature for 0.5 hours, repeating this cycle 5 times. If no cracking, stickiness, or depression occurs, it is of high quality.
4. Oil Resistance: Soak the sleeve in a mixture of 70# gasoline and 10% toluene for 5 minutes. No discoloration or stickiness indicates high - quality and qualified products.
5. Wear Resistance: Tested by the Akron Abrasion Test, a quality difference of less than 0.07 indicates high quality.
6. Tensile and Impact Strength: A high - quality sleeve has good tensile strength (25 - 30Mpa at room temperature) and impact strength (notched: 35KJ/M2 at room temperature, - 40℃/24h is 5KJ/M; unnotched: continuous).
7. Anti - ultraviolet: The Safe Protector has good anti - UV performance, especially the black one which contains added carbon black to enhance this property.
8. Antistatic: Mainly used in construction machinery and for cable protection, in underground or dry environments, a sleeve with strong antistatic properties should be chosen to enhance the antistatic performance of internal components like hydraulic pipe fittings and protect hydraulic pipes in harsh conditions.
