PC melting temp is approx 265 deg C, however its glass trans temp is 145 deg C - begins to 'soften'. Working limits are therefore below this value
what is lpgs melting point
How is polycarbonate made How is polycarbonate made
Tin is a metal,it exist in solid form. It have a low melting temperature of 232 C (449.47 F).
Polycarbonate is a tough and versatile plastic used in bulletproof windows, cellphone casings and eyeglasses. Dr. Hermann Schnelle of Bayer in Germany invented the polycarbonate resin in 1953, just a week before Dr. Daniel Fox of General Electronics made the same discovery. Lexan is the brand name of polycarbonate.
Because phenol formaldehyde is a resin it is usually a mixture of chain lengths and cross linking. For this reason, you would not expect it to have a fixed melting point - rather it would usually have either a melting point range or a decomposition temperature (depending on the structure). As an example, the company Polyols and Polymers lists the melting point range of their POLYTONE PF 201 product as 700C-850C while their POLYTONE AP 132 product has a "softening point" of 970C-1100C but no melting point. Bakelite - which is one of the many types of phenol formaldehyde resin - is a thermosetting plastic which has no melting point; it has a decomposition point. As an example, the Bakelite manufactured by Jiacheng-Chem Enterprises Ltd. has a listed decomposition point range of 240~ 280°C. Again, because it is a mixture of polymer sizes and degree of cross linking, it doesn't have just one fixed temperature; it has a range over which the many different molecules will decompose. The temperatures under which phenol formaldehyde will melt, soften, or decompose are also affected by the amount of residual monomers still present in the polymer matrix.
The cost of polycarbonate roofing depends on many things like how strong the roofing is and how much you buy. The cheapest polycarbonate roofing available costs around $10 and the most expensive ones costs around $80.
We are wondering if you could provide to us the figures that would allow us to compare polycarbonate roofing costs versus regular shingle costs?
One advantage of a polycarbonate roof is that it is much less expensive than a glass roof. They are also easy to manipulate if you plan on installing them yourself.
Plastics don't have specific melting points. The melting point depends on a large number of factors and is more likely to be a range rather than a precise point as it would be for a small molecule. The melt temperature for ABS is usually somewhere in the vicinity of 378 K, just above the boiling point of water. It softens around 90 °C and melts around 105 °C. Maximum usable temperature is considered to be 80 °C.
This is the melting point.

Polycarbonate roofing is very durable and therefore long lasting. It is generally found to be longer lasting than other materials used in the same instances. It is nearly unbreakable and withstands almost any weather situation and temperature. It is use primarily for patio covers, carports, sheds, and even skylights.
well dampalon is a polycarbonate material used fr roofing and facade treatments.....a translucent and a very light acrylic material .
No basic Difference between melting point and Drop point.
assuming it is its own melting point NOTHING which is why its a MELTING point
deffine what is melting point?
