How to choose stabilizers in the calcium and zinc stabilizer soft products industry

PVC wire and cable

PVC stabilizer is a key research topic in the industry after the EU member state RoHS Directive clearly pointed out, in which lead and metal separator composites are the key elements in PVC stabilizers.

Wire and cable stabilizer: Wire and cable is relatively too soft, and the general tackifier will be more than 50 parts. For wire products, the key requirements are as follows:

1, light color material requires the production and manufacture of weather-resistant and discolored,

2, dark coffee pigment requirements do not precipitate, good saturation,

3. Congo Red Time. Of course, different manufacturer requirements are not the same, such as dielectric strength, anti-patina and so on.

Soft products stabilizer: including artificial leather, inflatable products, transparent soft tablets, which can be divided into polyurethane foaming stabilizer and block surface layer stabilizer, for injection mold processing technology, this type of stabilizer stabilizer has always been barium zinc, barium cadmium zinc stabilizer as the core, composite lead for such products is very small. The stability of the front and lower lobes of barium stearate is balanced, which has a good cooperation and promotion effect on polyurethane foaming, so the stabilizer for polyurethane foaming is barium zinc as the core, and the liquid is also a powder equipment machinery and equipment, and the ancestral secret recipe is relatively simple.

Calcium and zinc stabilizer for soft products

For the stabilizer of injection molding processing of ecological environmental protection, the key will encounter the following difficulties:

1, off the roller, mainly melting difficulties, poor melting leads to plastic particles do not cover the roller, may also be the precipitate left on the roller to cause the roll;

2, paste or printing packaging is poor, which is obviously the difficulty of precipitation, stabilizer ingredient precipitation is the key reason;

3, polyurethane foam stabilizer, it is easy to appear the difficulty is that the bubble hole is too large and broken, to fully consider the stabilizer component on the polyurethane foaming damage;

4, transparent stabilizer, powder equipment and equipment stabilizer transparency can also do a good job, to fully consider the compatibility of the binder and stabilizer components, even if just produced and processed out of the transparency is very good, put a period of time is also very likely to have precipitate and more and more opaque, or damage the second half of the performance parameters.

5, shoe sole material stabilizer: the key is in the application of flat sandals, low-end Converse canvas shoes soles. The key to the stabilizer of plastic shoes is also concentrated in composite lead, the selection of ecological environmental protection stabilizers has long been very easy, can completely replace the composite lead production and processing of shoes that guarantee the requirements, but the difficulty of ecological environmental protection has not led to abundant attention, but also because the key is low-end products, the lack of traditional and technical professionals in the production process is the key reason why ecological environmental protection cannot be promoted.

PVC transparent soft products

In recent years, the key difficulty of PVC polyurethane foam shoes is the difficulty of milky white discoloration, and this kind of discoloration is concentrated in the extreme heat temperature, which is likely to be related to the lead source.

1, set into the packaging bag alley in the humidity is too heavy condition, it is easy to have rust color, take it out and put it will slowly dissipate.

2, it is possible to see that some part of the light has discoloration, and the LED backlight part is better.

3. The foaming temperature of polyurethane during injection mold processing is 200 °C ~ 230 °C, and the stability of the stabilizer is not enough at this high temperature.

4, transparent stabilizer: transparent steel wire hose, network administrator, transparent wire, transparent plastic sheet, membrane this selection of transparent stabilizer, in addition to transparent wire, other can use organic tin stabilizer, but in recent years, the taste of organic tin and ecological environmental protection criticism has gradually been gradually attached great importance to by the industry. The selection of raw materials for transparent stabilizers for ecological environmental protection should be the key to fully consider the compatibility with epoxy resin glue and binder, and the selection of hydrotallite is very critical.

Key difficulties encountered with transparent stabilizers:

1, transparent wire patina, can be added to the system management of appropriate anti-patina agent;

2, the background color is dark, which is related to the selection of hydrotalite and the demand for zinc salt;

3, poor transparency, in addition to the selection of raw materials, but also related to the degree of melting, improve the stabilizer's melting professional ability is the key, transparent PVC as far as possible is completely melted PVC, there is a little poor melting is not transparent.

4. Select the internal and external lubrication, be sure to fully consider the compatibility between the slip agent and the tacking agent, otherwise it is easy to precipitate in the second half.
