TPE Material Developed for Medical Tubing
Medical Grade Thermoplastic Elastomer is a TPE material designed for medical-device infusion tubing.
It combines the flexibility and elasticity of rubber with the processing characteristics of thermoplastic materials. According to the supplied product information, the material is environmentally friendly and does not contain harmful components such as phthalates.
The material provides good biocompatibility, flexibility, elasticity, transparency, chemical resistance, non-migration characteristics, and processing performance.
Typical applications include infusion tubing and dialysis tubing. These products require a soft material that can bend during use while also providing transparency for visual observation and stable processing during tube extrusion.
Softness, Elongation and Mechanical Data
The typical infusion-tube material has a Shore hardness of 23D and a density of 0.89 g/cm³.
Its melt index is 3 g/10 min. Tensile strength at break is at least 16 MPa, while elongation at break is at least 700%.
Tear strength is at least 65 kN/m.
The high elongation supports bending, connection, and flexible handling of tubing. The relatively low hardness helps produce a softer tube body.
Additional items listed in the supplied product data include a pH difference of no more than 1.0, heavy metal content of no more than 0.1 μg/ml, cadmium content of no more than 0.1 μg/ml, and no unacceptable biological hazard.
These supplied parameters provide a practical basis for evaluating Medical Grade Thermoplastic Elastomer for the stated tubing applications.
Tubing Requirements Should Be Defined Before Sampling
Infusion and dialysis tubing require careful consideration of flexibility, transparency, compatibility, and processing stability.
During purchasing, buyers should specify the intended application, target hardness, tube diameter, wall thickness, required transparent appearance, extrusion equipment, and subsequent connection method.
Hardness, melt index, and elongation can influence tube feel, extrusion behavior, and bending performance.
For this reason, sample tube extrusion is useful before batch production. Buyers can evaluate tube dimensions, transparency, rebound, flexibility, and surface condition using the actual processing equipment and product structure.
For specific medical-device projects, relevant regulatory and verification requirements should be confirmed according to the customer's location and intended product use.
Material Selection and Process Coordination
Diyou New Material supplies TPE modified pellets for medical and healthcare applications.
Its production base includes raw material handling, extrusion modification, injection molding, and performance testing. The technical team can support material selection according to required tubing hardness, flexibility, and processing conditions.
Quality management for purchasing, production, inspection, and finished-product release follows an ISO 9001 quality management system.
Through formulation design, process control, and performance verification, Medical Grade Thermoplastic Elastomer can be evaluated through sample testing and later batch purchasing according to the actual infusion or dialysis tubing requirements.
