The present invention provides thermoplastic polyurethane particles, which are formed in a continuous matrix phase from a thermoplastic polyurethane resin and have a particle diameter of 200-500 m. In a differential scanning calorimetry (DSC) curve of the thermoplastic polyurethane particles, derived from the analysis of a temperature rise of 10 C./min by DSC, a peak of the cold crystallization temperature (T.sub.cc) is shown at a temperature between the glass transition temperature (T.sub.g) and the melting point (T.sub.m). The thermoplastic polyurethane particles have a compression degree of 10-20%.

The present invention provides polylactic acid particles, which are formed in a continuous matrix phase from a polylactic acid resin and have a particle diameter of 1 to 100 m. In a differential scanning calorimetry (DSC) curve of the polylactic acid particles, derived from the analysis by DSC using a temperature rise of 10 C./min, a peak of the cold crystallization temperature (T.sub.cc) is shown at a temperature between the glass transition temperature (T.sub.g) and the melting point (T.sub.m). The polylactic acid particles have an aspect ratio of more than or equal to 1.00 and less than 1.05 and a roundness of 0.95 to 1.00. The polylactic acid particles have a flow time of 20 to 30 seconds.

Apparatuses and methods for making uniform spherical beads are disclosed. Specifically, the uniform spherical beads are made by dropping droplets on a droplet rolling part, creating beads by rolling the droplets on the droplet rolling part from one spot to another spot, and collecting the beads by a beads collector.

An initial processing of natural raw rubber through an initial processing machine, comprising the steps of: (a) providing a coagulated latex which contains water and volatile compositions; (b) dewatering the coagulated latex through a screw-pressing process to remove free water; (c) forming a first pretreated latex material; (d) aging the first pretreated latex material through an aging process to remove water and volatile compositions; and (e) forming a final product of aged latex material. The screw-pressing process makes use of the temperature and pressure increase along the elongated channel structure. The aging process makes use of the further temperature and pressure increase of the rubber materials, together with the screwing effect of the screw-shaft component, the squeezing effect of the nozzle and additional heating at a particular location, which is around the mouthpiece of the nozzle to complete the aging process, which is energy saving, effective and efficient.
