Riempimento in TPU Materiale composito in plastica rinforzata con fibre di vetro lunghe Uso ingegneristico del marchio LFT-D

What is the TPU material?

TPU is thermoplastic polyurethane, which is a kind of polyurethane that can be plasticized by heating and dissolved by solvent. Compared with the mixed and cast polyurethane, the chemical structure of thermoplastic polyurethane has no or little chemical crosslinking, its molecules are basically linear, but there is a certain amount of physical exchange.

The concept of physical exchange, as it is called, was developed in 1958 by SchollenbergeC. First of all, it is proposed that there is a "connection point" between linear polyurethane molecular chains that is reversible in the presence of heat or solvent, which is not actually chemical crosslinking, but plays the role of chemical crosslinking. Due to this physical crosslinking, polyurethane has formed the theory of polyphase morphology structure. The hydrogen bond of polyurethane strengthens its morphology and makes it withstand higher humidity.

According to soft segment structure can be divided into polyester type, polyether type and butadiene type, they contain ester group, ether group or butadiene group respectively. According to the hard segment structure, they can be divided into aminoester type and aminoester urea type, which are obtained from diol chain extender or diamine chain extender, respectively. The common division is polyester type and polyether type.

Why filling Long Glass Fiber?

I compositi rinforzati con fibra di vetro lunga possono risolvere i tuoi problemi quando altri metodi di plastica rinforzata non forniscono le prestazioni di cui hai bisogno o se vuoi sostituire il metallo con la plastica. I compositi rinforzati con fibre di vetro lunghe possono ridurre in modo conveniente il costo delle merci e migliorare efficacemente le proprietà meccaniche dei polimeri tecnici e aumentare la durata formando fibre lunghe per formare una rete di scheletro interna rinforzata con fibre lunghe. Le prestazioni sono preservate in un'ampia gamma di ambienti.
