项目名称	聚醚型 TPU 树脂生医级
Description	ISOTHANE 5000 series products are polyether based thermoplastic polyurethanes. They exhibit excellent bio-compatibility, hydrolytic resistance, fungus resistance, and low temperature performance properties. These products can be injection molded, blow molded, and extruded.
Supply and Storage	ISOTHANE TPU resins are supplied in pellet form packed in 25kg moisture proof bags. All TPU resins have been dried before packing. ISOTHANE TPU resins should be stored in cool and dry environment in their original containers until be used. Storage temperature should not exceed 30°C. If only a portion of TPU resins was used from a bag, the remainder of TPU resins should be tightly closed.
Drying	TPU resins are hygroscopic and pre-drying of TPU resins is always a necessary step before processing. Depend on the climate, the granule exposed to the atmosphere will absorb moisture very quickly. The moisture might bring about partial degradation of polymers and the formation of bubbles or streaks in the molded and extruded parts. In order to ensure the efficient and successful processing into quality parts, the moisture content in TPU resins is recommended less than 0.02%. A desiccant-bed-type hopper dryer is recommended for drying ISOTHANE 5000 series. The dew point of the inlet air should be in the range of -30 to -40°C. About the recommended drying conditions, please view ISOTHANE individual data sheets.
Processing - Extrusion	Barrel and Motor High torque drive capacity at low speed Vented or standard barrels acceptable Screw Compression ratios between 2:1 and 3:1 Minimum L/D of 30/1 Feed Throat Vertical and tangential Water cooling is recommended Screen Pack Streamlined breaker plates with screen packing is recommended Typical 40/80/80/40 mesh screens Die Streamline with good temperature control Land Length is generally 10 to 15 times the part thickness Coat-hanger manifold-type dies are recommended for extruding film and sheet Crosshead dies are recommended for wire, cable and hose jacketing Side-fed rotating dies are recommended for blown film About the recommended extrusion temperatures, please view ISOTHANE individual data sheets.
Processing - Injection Molding	Barrel and Motor High torque drive capacity at low speed Vented or standard barrels acceptable Screw Compression ratios between 2:1 and 3:1 Metering screw with gradual transition zone Injection Pressure Typical 6,000 to 15,000 psi Hold pressure 60 － 70% of forward time Injection speed Slow to moderate Depends on gating, wall section and flow length About the recommended injection molding temperatures, please view ISOTHANE individual data sheets.
Coloring	Generally, ISOTHANE TPU resins are supplied in their natural color. They can be colored by blending with pigment or pigment master batch. Using master batch based on TPU is recommended. Other master batch based on polyethylene or polystyrene is suitable to a limited extent. All colorants employed in TPU resins must be pre-dried before processing. The normal addition of pigment or pigment master batch is 0.2%-0.5% or 1-3%.
Additives	Various additives can be used to enhanced the properties of ISOTHANE TPU resins, e.g. anti-blocking agents, antioxidant, UV stabilizers or release agents. Most additives supplied as master batches are available. But not all additives are compatible with ISOTHANE TPU resins. It is recommended to inquire of your suppliers or our technical service before compounding.
Recycling	For ISOTHANE TPU resins, up to 20% of regrind may be recycled with virgin material depending on finished parts requirements. The regrind material has to be kept free of contamination, diced and dried before re-using. The material which has been contaminated, discolored or degraded is not suitable for recycling. TPU resins may decrease desired properties, e.g. hardness and mechanical properties, due to improperly mixing with regrind. Regulatory or testing organizations (e.g., UL) may have specific requirements limiting the allowance amount of regrind. Certain quality requirements laid down in specifications may exclude the use of regrind material.
Healthy and Safety Information	Before working with these products, it is essential that all operators are aware of the healthy and safety precautions. ISOTHANE TPU resins can be processed or machined over a wide range of temperature. There can be some smoke formation during processing. The smoke that contains some decomposition substances of TPU or additives may cause irritation to human body. Generally, the temperature does not exceed 240°C that can reduce decomposition formation. An effective extraction system, especially in the melt outlet zone, is necessary. The detail information concerning healthy and safety can be available in safety data sheets (SDS) or contact our technical service.
Disposal	ISOTHANE TPU resins present no hazard to the environment or water. They can be dumped on municipal landfill or in a waste incineration plant. The official regulations on waste disposal should be observed.
