PU is shorten name of Polyurethane

TPU is shorten name of Thermoplastic Polyurethane.

Look, they are only differences on shorten.

The Samlongda high pressure LAYFLAT HOSE

From 2009 samlongda developed new type layflat hose with one-step extrusion technology to nowdays, it passed almost 5 years.

Firstly, samlongda engineer Mr. Tim Zang and our diretor Mr. Zeng combine China extrusion machine with wrap structure which is highly similar technology to Korea Ponaflex and Sunflow America. We become the first factory in China who control the new model layflat hose with abroad. At the same year, we export this new hose to South asia farm market. And the new layflat get very warm welcomed by farm. Becuase it reduce the weight at least 10% (small sizes)-30% (big sizes) than tranditional layflat.   Meanwhile, the working pressure is from 4bar. (PS: at tranditional layflat, heavy duty is 4bar).
It mean the farmer pay cost of economic duty and buy the pressure of heavy duty hose.

Samlongda team don't stop the step on developement.  One Spring of 2011, we increase the extrusion machine into 10 lines.  And working pressure of layflat is up to 6-9bar(87psi-130psi).

Time fly fast !  At 2013, we sucess into working pressure 10.5bar heavy duty layflat hose for sizes:3/4" to 3".
Many mining pump system take our layflat from that time.

In the near future of 2014-2015, samlongda layflat team is going to develope higher pressure for big sizes, specially 6inch to 12 inch.
