Polymer material is one kind of natural and synthetic substances ,which is composed of very large molecules. Natural polymers are the major building blocks of living organisms, including proteins/polyamides, polynucleotides (RNA, DNA), and lignins (coniferyl alcohol compounds).
Polymer processing is the science technologies of being converted raw polymer materials into finished or semi-finished products of useful shapes and structures through various physical and chemical reaction, shaping, compounding mixing ,extrusion etc.
This foundational step plays an important role in various industries such as automotive, aeroplane ,medical, packaging, and electronics etc.
For researchers, the two roll laboratory mixing mill for polymer provides an ideal environment to evaluate, blend, and optimize polymer compounds in labs.
The polymer processing is an essential procedure in both commercial manufacturing and R&D laboratories to test new formulas, create prototypes, and refine final products.
When the raw polymers material are formed into finished products , it involves a series of polymer manufacturing processes.
First Step : The polymer material are fed onto the open mixing mill ,additives are then added into the polymer , so that achieve the final modification to the properties of the raw polymer as desired.
Second Step: The polymer material are blended and mixed uniformly , to create the desired shape.
Generally , polymer manufacturing processes can be divided into continuous processes and batch processes. For continuous process, the raw polymer material is fed in continuously and the final product flow appears continuously ,for example extrusion process . Basically ,the material can be convert into to pellet & granule, powder ,sheets ,fibers, tubes etc.
For batch or cyclic processes, such as mould processes, there is a higher probability of batch-to-batch variation and lower efficiency due to unproductive parts of the cycle (down time).
Several Main Factos Need To Consider in Polymer Processing
* Material Type: Thermoplastics can be remelted, while thermosets set permanently after curing.
* Additives & Fillers: Reinforcements (like glass fibers), stabilizers, and plasticizers affect properties like strength, UV resistance, and flexibility.
* Process Temperature & Time: Precise control directly effect the quality of products, ensure it consistently.
* Mixing & Dispersion: In order to ensure the filler and additives dispersed uniformly and evenly, the mixing process is very vital, it is often performed using internal banbury mixers, kneader or open mixing mills.
Wide Applications Across Industries
The polymer is widely used in various industries,including:
* Automotive Bumpers, Car Parts , dashboards, under-the-hood parts
* Medical ,Catheters, surgical instruments, drug-delivery devices
* Construction,Pipes, insulation, flooring, sealants
* Consumer Goods,Toys, packaging, home appliances
* Electric Electronics Housings, connectors, insulation
* Fiberglass, nylon bearings, plastic bags, polymer-based paints
* Clothing,coatings
* Personal Protective Equipment
