Description |
ISOTHANE 2000 series products are poly(caprolactone) ester based thermoplastic polyurethane. They exhibit excellent mechanical properties, hydrolysis resistant, oil resistance and outstanding low compression set. These products can be injection 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%. |

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. |
|
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. |
|
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. |
