- Q: Is the plastic with high melting index good?
- Its test method is: first let the plastic particles in a certain time (10 minutes), under certain temperature and pressure, melt into plastic fluid, and then through a diameter of 2.1mm tube g (grams) outflow. The greater the value, the better the processability of the plastic material, the worse the contrast.
- Q: What is the difference between EPS plastic particles and PS? What materials are represented?
- PS does not have no foaming agent. It is divided into GPPS (ordinary type) and HIPS (impact type). It is used for injection molding, extrusion, television, telephone shell, cup and so on.The main ingredients are polystyrene.
- Q: What kind of material is the plastic bag commonly used in supermarkets now?
- Another is PP or OPP, which contains bread and crackers. The material is smooth and very transparent, but the tightness is not very good and there is no tension.
- Q: What is the concept of plastic raw materials for turnover containers?
- Plastic turnover box, other features: 1) plastic turnover box outer dimension refers to the maximum size of the logistics box cover. 2) the plastic turnover box has no standard inner concave, and the case size is 18mm. 3) the carrying capacity of a plastic turnover box means that the load is uniformly placed within the range of the environmental temperature. 4) the effective working temperature of the plastic turnover box is -25 DEG C - 40 DEG C. 5) plastic turnover boxes can be stacked for storage, saving space.
- Q: What raw material (HDPE) made of plastic bags, high transparency, good sense of light master?
- Synthetic resin is the most important component of plastics, and its content in plastics is generally between 40% and 100%. Because of the large amount and the nature of the resin, which often determines the nature of plastics, people often think of resin as a synonym for plastics. For example, PVC resin is mixed with PVC plastic, phenolic resin and phenolic plastics. In fact, resin and plastics are two different concepts. Resin is an unprocessed primitive polymer that is used not only in plastics but also as raw material for paints, adhesives and synthetic fibers. In addition to a very small number of plastic containing 100% of the resin, the vast majority of plastic, in addition to the main component resin, but also need to add other substances
- Q: What raw materials do plastic color printing plants use?
- Mainly plastic film and ink, the film is generally in accordance with the nature and requirements of products such as PVC film, POF film
- Q: PVC what is the difference between raw and recycled raw materials?
- Products using recycled materials are brittle, easy to break or burst, very durable.
- Q: How to test plastic raw materials?
- Thermal stability test of size and appearance quality. Place the product in a 8020C oven, 24H, and cool down to 2350C (2H). Measure the size of the same measuring point before and after the test, and calculate the percentage change rate. And observe the appearance quality changes, dimensional change rate of <0.2%, appearance is not allowed to have deformation, crack, expansion, surface gray, discoloration and other phenomena.
- Q: What does MFI mean in PC material?
- The measurement of MI is usually based on the standard method of ASTM D1238. It is the principle of the plastic or resin into the metal sleeve of a fixed inner diameter, and heating the plastic or resin after melting, and then give some load on the piston, the piston on the weight of the molten plastic has been squeezed out from a small hole in the charge, and calculate the weight and squeezed out of plastic. This measuring method, because of the same material, the sleeve barrel inner diameter, load, and temperature are fixed, so in addition to test MI, can also be used for the determination of density, viscosity, and melt shear rate, shear stress... etc.
- Q: What are the raw materials made of modified plastics?
- Broadly speaking, the modification is to change the original performance, such as TPU, flame retardant, anti UV and so on; a narrow sense, the industry will be the new material of TPU polymerization, production is not called modified, and those who buy TPU new material made of flame retardant TPU, called "back modified". The modification process involves adding some resins or additives.
