Liquid pipe connecting pipe protective sleeve
I. Raw Material Specification
The raw material adopts imported medical-grade silicone with a Shore A hardness of 50, a high-end raw material dedicated to medical devices. It complies with relevant medical biosafety standards and delivers exceptional safety and biocompatibility in application.
This material features high purity, odorlessness and zero impurities. It contains no heavy metals, toxic and hazardous substances or allergenic components, boasting outstanding biocompatibility. It can remain in long-term contact with human medical fluid media without bleeding, permeation or deterioration, eliminating the risk of contaminating medical pipelines and blood samples.
Medical silicone at Shore A 50 balances excellent flexibility, resilience and structural stability with moderate hardness. It fits tightly to fluid pipeline structures and accommodates dynamic operating scenarios such as pipeline bending and plugging/unplugging. It also offers outstanding resistance to tearing, aging, high and low temperatures, and withstands routine medical disinfection environments, resisting deformation, cracking and aging failure over long service lives.
In addition, the material has a smooth, dense surface that resists dust and bacterial adhesion with favorable self-cleaning properties. It fully meets the stringent cleanliness, safety and stability requirements of medical applications, making it the preferred raw material for blood department medical pipeline fittings.

III. Production Process
This product adopts an integrated vulcanization molding process. The entire production strictly complies with Good Manufacturing Practice (GMP) for medical devices, with rigorous control over every production procedure to guarantee dimensional accuracy, cleanliness and service performance of finished products.
Production Environment:The full workflow including production, molding, inspection and warehousing is completed entirely in a medical-grade dust-free clean workshop. The workshop undergoes regular dust removal, sterilization and air purification to strictly limit particulate and microbial counts. This effectively prevents dust, bacteria and impurities from adhering to product surfaces during manufacturing, securing high cleanliness grades from the source to fit sterile medical application scenarios.
Core Molding Process:High-temperature integrated vulcanization molding technology is applied. Imported Shore A 50 medical-grade silicone raw materials are subjected to one-shot hot-press vulcanization via precision molds.
Compared with splicing and secondary processing techniques, integrated vulcanization eliminates splicing gaps and risks of secondary adhesive failure. The finished parts feature a dense, uniform monolithic structure with superior sealing integrity and structural coherence, effectively preventing cracking, leakage and detachment during service.
Precise temperature and time control during vulcanization maximally preserves the elasticity, toughness and biosafety properties of medical silicone, ensuring consistent hardness, dimensions and performance across all production batches.
100% Full Inspection & Warehousing Procedure:After molding, professional quality inspectors conduct 100% full-item inspection in a dust-free environment. Key indicators including dimensional tolerance, surface smoothness, structural tightness, elasticity & toughness, and cleanliness are thoroughly tested. Defective units with blemishes, deformation or contaminants are screened out. Only fully qualified products are categorized and standardized for warehousing, achieving a 100% pass rate for all factory shipments.
