PLASTIC MATERIALS & PLASTICIZING

Plastic Materials & Plasticizing

Plasticizing characteristics and screw matching for commodity plastics, engineering plastics, glass fibre, flame-retardant and corrosive materials.

How material number and batch changes are incorporated into plasticisation management

How material number and batch changes are incorporated into plasticisation management

Discrepancies in viscosity, water content and crystallization may still exist in different plate numbers, additives and batches of the same polymer. Material mechanisms, plasticiza…

How to judge whether plastic is a cut sensitive material

How to judge whether plastic is a cut sensitive material

Cutting sensitive materials are subject to overheat degradation at high turn speed, high back pressure or narrow gap and require mild plasticization. Material mechanisms, plasticiz…

The relationship between plastic thermal stability and the permitted time of stay

The relationship between plastic thermal stability and the permitted time of stay

The oxidation, cracking, interconnection or devolvation rate of the material at the processing temperature determines the safe stay time. The relationship between thermal stability…

How plastics affect the speed of plastics.

How plastics affect the speed of plastics.

The energy required to heat up a unit mass is determined by the heat, which affects the internal temperature of the particles, which together constrains plasticization. Material me…

How does the density of the lava modify the size of the plastic emitter?

How does the density of the lava modify the size of the plastic emitter?

Note plastics are often based on PS, and the solid and melting density of different resins alters the actual injectable weight. Material mechanisms, plasticization parameters, risk…

The role of glassified temperatures and melting points in temperature setting

The role of glassified temperatures and melting points in temperature setting

The glassified temperature describes the zone in which the chain begins to move, and the melting point is used for the melting of the crystal area, which determines the basic bound…

Impact of wide and narrow molecular mass distribution on plastic stability

Impact of wide and narrow molecular mass distribution on plastic stability

The wide distribution differs from the narrow distribution of resins in the low shear flow, melting strength and high shear response, changing the replicability of filling and plas…

How the polymer molecular mass affects the melting strength and mobility

How the polymer molecular mass affects the melting strength and mobility

The increase in molecular volumes usually increases the melting strength, resilience and viscosity, with a consequent increase in the plastered pressure and plasticized load. Mater…

Difference between crystallization and plasticization of non-crystalized plastics

Difference between crystallization and plasticization of non-crystalized plastics

The crystallity material has a distinct melting zone and volume contraction, and the non-clinical material is gradually softened above the glassified temperature, so the temperatur…

Disparities between the structure and processing of thermoplastics and thermosolid plastics

Disparities between the structure and processing of thermoplastics and thermosolid plastics

Thermal plastic resins are softened and can be melted again, and thermal solid systems are solidified and form a conjunctivity network, and the plasticization equipment is complete…
