A business using the cycle inventory method might count different items at different rates, based on the level of turnover or demand for that particular item. method of keeping track of inventory by performing inventory counts constantly, or on a frequent and regular basis, instead of once per year or once per quarter.
Effect of Heat. The melting point of polypropylene is about 165Â°C and while it does not have a true softening point temperature, the maximum processing temperature of the fibre is approximately 140Â°C. Prolonged exposure to elevated temperatures will cause degradation of the fibre, but anti-oxidants are incorporated in polypropylene fibres to protect them during processing and at normal service temperatures.
Polypropylene (PP) is a thermoplastic. It is a linear structure based on the monomer CnH2n. It is manufactured from propylene gas in presence of a catalyst such as titanium chloride.eside PP is a by-product of oil refining processes. Most polypropylene used is highly crystalline and geometrically regular (i.e. isotactic) opposite to amorphous thermoplastics, such as polystyrene, PVC, polyamide, etc., which radicals are placed radomly (i.e. atactic).
