Density of Plastics: Technical Properties. Density measures the mass per unit volume. It is calculated by dividing the mass of the material by the volume and is normally expressed in g/cm3. The density of a plastic sample may change due to change in crystallinity, loss of plasticizers, absorption of solvent, etc.
Polypropylene yarn is NOT harmful for the environment: 1. It is mass dyed (no water is polluted during its production as compared with thousands of liters when producing one kilogram of cotton, the colours are permanently anchored in polypropylene yarn and do not subside into your skin)

Nov 02, 2017· Polypropylene is produced via addition polymerization of propylene. Polyester materials are highly used in textile industry. Polypropylene has its major application as a packaging material. The main difference between polyester and polypropylene is that polyesters can absorb some amount of water whereas polypropylene does not absorb water at all.

Polypropylene is resistant to many polar liquids such as alcohols, organic acids, esters, and ketones. Aliphatic, aromatic, and halogenated hydrocarbons will swell polypropylene (Table 6.19).The extent of swelling will depend upon the percentage of crystallinity (the less crystalline and more amorphous the material, the greater the swelling).
What Are the Properties of Polypropylene? (with pictures)
When examining the differences between polyethylene and polypropylene materials, it can be summed up in a difference of structure that results in varying physical, thermal and chemical properties. These, in turn, translate to varying limits on temperature exposure, rigidity, permeability, sustainability, and optical properties.
Polypropylene offers ease of processing with excellent chemical resistance and good mechanical properties. Glass fiber-reinforced polypropylene has improved dimensional stability, resistance to warpage, rigidity and strength. Heat deflection temperature at 264 psi is increased up to 300 °F (150 °C) for 40% glass fiber reinforced polypropylene.
May 30, 2012· Nylon was produced as a replacement for silk to make fabrics and such materials. Nylon can be lustrous, semi-lustrous or dull. They can be subjected to high elongation. Nylon is resistant to abrasion, insects, fungi, and many chemicals. Polypropylene vs Nylon. Monomer of polypropylene …
Polypropylene is an economical material that offers a combination of outstanding physical, mechanical, thermal, and electrical properties not found in any other thermoplastic. Compared to low or high density polyethylene, it has a lower impact strength, but superior working temperature and tensile strength.
Polypropylene (also called polypropene, PP) has properties between that of LDPE and HDPE and is one of the most versatile polymers available. It is used in a wide variety of applications, including food packaging, textiles, plastic parts and reusable containers of various types.
