What is addition ratio of TPU material in agricultural film production and the effect of TPU to agricultural film
May 12 , 2023
Agricultural film is a type of plastic film used in agriculture for various purposes such as covering crops and protecting them from pests, weather, and UV radiation. The agricultural film is made in a single continuous process, where the plastic is melted and extruded through a die to form thin sheets. The sheets are then processed further to make the final TPU agricultural film. The composition ...

Why TPU been widely added to modify plastics
May 26 , 2023
Compound plastic are plastic materials that have been chemically or physically modified to improve their performance or characteristics. This can be achieved by adding additives such as fillers, stabilizers, plasticizers, or pigments to the plastic resin. The modification can also be done by incorporating a new compound or by blending two or more resins to produce a hybrid material with specific p...

What will the hardness of TPU influence the products and how to choose it
Jun 02 , 2023
It will leading to deformation or collapse of the product when the TPU material is too soft. It may become brittle and crack when the TPU material is too hard particularly for phone cases, watch bands or sport equipment products that require flexibility and durability. So, it is very important to choose appropriate hardness of TPU material. What will the hardness of TPU influence the products 1.Me...

How to solve the dark specks and spots on TPU extrudate or TPU injection products
Jun 25 , 2023
What cause dark specks and spots on TPU extrudate or TPU injection products ① Contamination in the raw material: TPU is sensitive to contamination from impurities present in the raw material. This can lead to dark specks and spots in the extruded or injection-molded product. ② Screw and barrel contamination: If the screw and barrel are not cleaned properly, leftover resin from previous r...

What defect caused by the long molding cycle time of soft TPU and how to avoid it
Aug 25 , 2023
The molding cycle time refers to the total time it takes for a complete injection molding cycle, including the stages of filling, cooling, and ejection. The molding cycle time of TPU (Thermoplastic Polyurethane) can have an influence on the properties of the final injection products. A long molding cycle time for soft TPU (Thermoplastic Polyurethane) products can potentially cause various defects....

Why the lower TPU hardness the lower processing temperature
Sep 08 , 2023
The processing temperature of TPU is influenced by several factors, including its hardness. Generally, lower hardness TPU grades have a lower processing temperature compared to higher hardness grades. This relationship can be attributed to the following reasons: Molecular Structure: The hardness of TPU is determined by the ratio of rigid segments (hard segments) to flexible segments (soft segments...

What is GRS certification
Oct 13 , 2023
GRS (Global Recycled Standard) is a globally recognized certification and labeling system for products made from recycled materials. The purpose of GRS is to promote the use of recycled materials, reduce the environmental impact of production, and provide transparency and assurance to consumers. By using products certified under the Global Recycled Standard, consumers can make more informed choice...

The proportion of MDI influence the embrittlement performance of TPU at low temperatures
Nov 03 , 2023
MDI is one of the key components used in the production of TPUs. It serves as the isocyanate component, reacting with polyols to form the polyurethane segments of TPU. The selection of MDI type and the ratio of MDI to polyols can affect the physical properties and performance characteristics of the TPU, including its low-temperature behavior. TPU formulated with a higher proportion of MDI generall...
