There are many types of nylon, but they all are polyamides of relatively low molecular weight (at least compared to PE and PP). Generally they are manufactured by reaction of diacids and diamines, although there are other useful methods. Nylons have strong interchain interactions which result in very strong tensile strengths(抗拉强度). For that reason their use is primarily in fibers.
PP is polypropylene. It is chemically similar to PE but is made from the monomer propylene (CH3CH=CH2). This can be prepared from fewer reactions than PE, but it is much tougher and stronger than PE, even after molding, because it has more self-crystallizing capacity. A lot of consumer goods are made from PP for this reason.
The polypropylene Young modulus is between 1,5 and 2,0 GPa.
Polypropylene is a thermoplastic polymer used in many applications..
PVC is the most common plastic used in book covering materials, and has been used for many years. Polypropylene has become more common recently. Both of these plastics have different handling characteristics. PVC is generally considered to be easier to fold and to conform to the shape of a book more readily, while polypropylene is usually a little more rigid. Sometimes PVC will stick to itself, particularly in warmer weather. Polypropylene is well known for it's non stick characteristics, in fact it is difficult to glue and even permanent marker can be removed from it, giving it superior life and resistance to damage and marking. Polypropylene is also acid free, and is considered to be an archival plastic. PVC is known to have a low level of acidity. PVC is cheaper than PP.
yes
Nylon is not biodegradable.
The difference between nylon and dacron rope is that nylon stretch but dacron dose not!
No, nylon and polypropylene are different types of polymers. Nylon is a synthetic polymer known for its strength and elasticity, often used in textiles and plastic products. Polypropylene is another type of synthetic polymer, known for its thermal resistance and chemical inertness, often used in packaging and textiles.
The difference between isotactic polypropylene and syndiotactic polypropylene lies in the arrangement of the propylene monomer units in the polymer chain. In isotactic polypropylene, all the methyl groups of the propylene units are on the same side of the polymer chain, while in syndiotactic polypropylene, the methyl groups alternate sides. This difference in arrangement affects the properties and crystallinity of the polymer.
The main difference between polypropylene and polyethylene is their chemical structure. Polypropylene has a more rigid structure, making it stiffer and more heat-resistant than polyethylene. Polyethylene is more flexible and has a lower melting point. You can also differentiate them by their density, with polyethylene being less dense than polypropylene.
Nylon 610 is a type of nylon that is derived from hexamethylenediamine and sebacic acid, while nylon 106 is not a commonly known type of nylon. The main difference is their chemical composition and properties, with nylon 610 having different characteristics compared to nylon 106.
anything "synthetic" including nylon, polypropylene, flees and rayon.
polypropylene, urethane
Cotton is natural fiber harvested from an organic, living plant, while nylon is a man - made fabric
Nylon rope is available at all hardware and boating supplies stores. Most ropes are made from cheaper plastic fibers like polypropylene. Nylon is reserved for places where the rope is handled and a softer feel is desired.
the construction is different, each have pros and cons
Nylon tips are louder, harder sound, and last longer. Plus if your drumsticks are colored and your toms are white, they keep the paint on the tip from marking your toms.
The polypropylene Young modulus is between 1,5 and 2,0 GPa.
