What is the difference between bopp and opp?
OPP stands for Oriented Polypropylene film, a thin plastic sheeting. BOPP stands for Biaxially Oriented Polyproplene, a clearer, stronger film used in many types of consumer packaging. It has consistent thickness and optical clarity, and offers better protection.

What is the difference between polypropylene and cotton?
cotton comes from a plant and polypropylene is man made. i think you already knew that though?
What is the difference between acrylic and polypropylene?
Acrylic is a type polymers used to make textile fiber found in things like fabrics and yarn . It can also be a type of paint. Polypropylene is a type of polymer that is used to make things like textiles, rope and carpeting. The difference between the two are its uses.
Polypropylene tensile modulus?
The polypropylene Young modulus is between 1,5 and 2,0 GPa.
What is difference between homo and co-polypropylene?
Homopolypropylene is made up of only propylene monomer units, while copolypropylene contains a mixture of propylene and other comonomer monomer units. This difference in composition results in variations in properties such as melting point, density, and chemical resistance between homo and copolypropylene materials. Copolypropylene is often used to improve impact resistance and flexibility compared to homopolypropylene.
What is the difference between bopp and cpp film?
CPP film is a plastic extrusion made of polypropylene. BOPP films are bi-directional polypropylene. CPP film is high gloss, has good transparency, is heat resistant, and water resistant.
Difference between bopp and opp?
The difference is noted there in the name of these two structures. BOPP stands for Biaxially Oriented Polypropylene which means it is stretched in both the machine and transverse direction while being manufactured. OPP stands for Oreiented Polypropylene which means it is stretched in only the machine direction. These two methods of manufacturing require different equipment and processing paramaters.
What is the melting point of polypropylene?
The softening temperature of polypropylene is 150 degrees Celsius. Its melting point is between 160 and 170 degrees Celsius.
What is the difference between PVC and polypropylene canvas?
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.

What is the difference between nylon and polypropylene?
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.

What are the similarities between thermo plastic and thermosetting plastic?
There are a few differences between the two. Thermoplastics usually contain additives to change the properties of the material such as polypropylene. Thermosets usually contain catalysts that change the state of the material at the molecular level. The main difference between thermoplastics and thermosets is that: -Thermoplastics can be re-melted and recycled fairly easily -Thermosets typically are cured and molded into shape and are not recycled as easily
