Question 1

What is BIOBASED TPU?

Accepted Answer

ECO BIOBASED TPU HOT MELT ADHESIVES － Goldthane ECO SERIES In 2015, UN set 17 sustainable development goals (SDGS). Especially SDGS 13 Climate Action, it is still possible to limit warming to 1.5oC and reduce Green House Gases of value chain. For difficultly reducing remaining emission, the effect could be offset by permanent removing equal amount of CO2 from air. To achieve the object, corporations set a goal that all supply chain should reduce 30% CO2 emission in 2030; furthermore, net zero emission in 2050. Biobased TPU would replace common petrochemical raw materials by plant. Bio-material is made from fermentation vegetation. Moreover, vegetation is a recyclable natural resource which would carry out photosynthesis in growth process. Planting vegetation would absorb CO2 from air to balance the effect from the Green House Gases emission and a nice characteristic of environment. In order to reduce emission of Green House Gases, we manufacture Biobased TPU which is made from plant. TUV (OK biobased) is currently the most authoritative bio-material certification mark in EU. CEN（CEN）“CEN / TS 16137：2011 establish calculation method for Determine the monomer, polymer, plastic material and Biobased carbon content. The 14C (CEN / TS 16137; US ASTM D6866) is the perfect way to measure Biobased carbon content of product or material. To identify biomass carbon and petrochemical source carbon, biomass carbon has distinctive carbon-14 content; however, petrochemical source carbon does not include carbon-14. By calculating rate of two type for Biobased content. In this standardize way, it could verify Biobased carbon content of product or material. TUV(OK biobased)： ★：Biobased 20%~40%； ★★：Biobased 40%~60%； ★★★：Biobased 60%~80%； ★★★★：Biobased >80% (the highest level) GOLDTHANE successfully developed Biobased TPU hot melt product, ECO series, which is approved by laboratory BETA that biobased content is more than 31%. Biobased TPU could apply for hot melt adhesive film、shoes material、armband、 waterproof adhesive strips and fabric pasting. Also, it could offer nice pasting result on Polyester、Nylon、cotton and so on. GOLDTHANE has the professional development team which is able to provide customize product or adjust formula according to your demand. GOLDTHANE would develop much more product of Biobased TPU and supply various specification out-put to contribute sustainable development for future. Biobased TPU hot melt adhesive Biobased TPU hot melt adhesive is a thermoplastic polyurethane particle. It is made from plant fermentation derived. By processing into film and heated bonded to the substrate or using T-die extrusion, coating onto a substrate material for bonding. The anchoring phenomenon during bonding, after hot pressing and cooling, the bonding would be completed shortly. It is a process of green environmental without solvent and advantageous to create a safe clean working environment without pollution. In the future, we would continue rolling out different hardness, process temperature, Non-yellowing and various Biobased TPU products. ★Biobased content20~40% ITEM ECO170 ECO170 ECO170 HARDNESS(Shore A) 76 A±3 76 A±3 76 A±3 TESTING TEMP.

Accepted Answer

Question 3

Hot melt adhesive film

Accepted Answer

Question 4

How to store Thermoplastic polyurethane

Accepted Answer

Avoid any moisture and exposure to sun. Products must be stored at dry, well ventilation place and keep in room temperature ( at 25℃ or 77℉ ).

Question 5

Common Ink carrier adhesives Uses and Applications

Accepted Answer

Helpful for shoe and textile industries such as screen printing, gravure printing, and spray ink.

Question 6

What is the characteristic of Ink carrier adhesives

Accepted Answer

TPU as ink carrier need to be used with solvent, the appearance is transparent with good tone condition and color rendering, it possess good abrasion resistance, flexibility and adhesion characteristic, it is the best product for ink or coating application.

Question 7

Common Solvent-Based Uses and Applications

Accepted Answer

It can be applied on shoe materials, textile lamination, fire hose, furniture (MDF board) lamination, and has excellent bonding strength to TPU, PVC, Polyester, nylon cloth and leather.

Question 8

What is the characteristic of Solvent-Based

Accepted Answer

We provide four different solvent-based TPU adhesive, general, non-yellowing, PCL and non-yellowing without organic TIN, has good solubility, good plasticity at low temperature and high crystallinity, good heat resistance, non-yellowing properties with wide range of viscosity, processing temperature.

Question 9

TPU

Accepted Answer

TPU (Thermoplastic polyurethane) is a pellet that can be processed by spinning, injection and extrusion to meet different needs. As it provides good elasticity, abrasion resistance, tensile strength and good flexibility, so widely used in shoe, textile, automobile and furniture industries…etc. Sun Yang provide four series of TPU for Fiber application, Hot Melt Adhesives, Solvent-Based and Ink carrier adhesives.

Question 10

What is the characteristic of Fiber application

Accepted Answer

It has good elasticity, abrasion resistance, high toughness, anti-slippery, oil resistance, waterproof, low melting temperature and good flexibility. In order to provides different results depends on the type of knitting method, we designed products with flow beginning temperature ranges from 100℃ to 160℃.
