我们的产品绢云母粉
在马来西亚采集的绢云母是属于云母类的天然细粒矿物。绢云母是细粒的云母，类似属于天然矿物类的白云母和伊利石。绢云母是通过更改长石矿在受到水热蚀变的地方形成，这一般上与铜、锡，或其他热液矿床相关。绢云母是水合硅酸钾铝，其矿物组合及结构与高岭土类似。因此，它拥有云母及黏土矿物的特性，比重介于2.6-2.9。这独特的马来西亚绢云母十分柔滑，颗粒也十分纤细。
在去除覆盖层后，天然的细粒黏土从土地里挖掘出来。然后，黏土进一步地通过湿法或干法加工至颗粒大小和档次不同的云母粉。
云母可以用于很多用途，比如涂料及化妆品、橡胶业中的模具润滑剂、焊条电极的助溶剂，以及用来加固塑料。
云母在过去20年来受到化妆品行业的主要领先品牌广泛应用在粉底以及唇膏之类的彩色化妆品。绢云母令皮肤更加平滑，同时更加黏合皮肤，使到脸上的妆得以更持久，不会轻易脱落和起皱。它可令色彩一致，亦相对具有透明度，适用于所有的皮肤。

Untreated Sericite Mica
Untreated sericite mica (usually just called sericite mica) is colourless and will increase the translucency of your products. It will reflect light, but it tends to be low lustre. It offers low coverage, so it’s suitable for light to medium foundations and eye shadows, and it won’t clog your pores. It isn’t great at absorbing oils, and people with oily skin might find that their colour turns ashy through the day (this is especially an issue for darker skinned women with oily skin!).
Good for light to medium coverage for normal to dry skin.
Summary for Untreated Sericite Mica
Usage rate:
Up to 100% in powdered products.
Advantages :
- Its ability to block UV radiation and prevent skin cancer
- Provides shine and luster thus, giving a pearl effect
- Stable and chemically inert
- Partial reduction of pearl pigments, thereby reducing costs
- Imparts softness and smoothness
- High coating ability
- Provides a matte finish
Suitable To Be Used In :
- Pressed powders
- Body powders
- Liquid makeup
- Lipstick
- Nail polish
Whiteness or opacity:
To make darker skin colour lighter, to cover up imperfections.
Translucency:
The base itself is almost invisible once applied. This is why we use sericite. It is colourless and increases translucency. Untreated sericite is the most translucent of all the sericites.
Skin protection:
Not really applicable with untreated sericite mica.
Slip:
The product provides a good “nice feel” effect when rub on the skin. It offers slip and glide on your skin with a silky feel.
Absorbency:
Your colour will remain true throughout the day and not morph into something due to environmental stresses or skin oils. It is not suitable for people with oily skin as the primary ingredient.
用于化妆品的绢云母粉
经过多年的研发，我司的绢云母粉已经广泛应用在以下的化妆品系列:包括粉底,爽身粉, 液状粉底, 唇膏, 指甲油。
Surface Treated Sericite Mica – Treated with Silicone
Surface treated sericite mica- sometimes called silicone mica – is treated with silicon to increase the water resistance, increase adhesion and make it more free flowing. It is shinier than the untreated sericite mica, so it will reflect light and reduce fine lines. However, it is not suitable for elderly people with deep skin lines as it will show more wrinkles on their skin. It will absorb oil to keep your colour true throughout the day, so it’s a great choice for people with oily or dark skin. It feels silky smooth on application and on your skin.
Good for medium to full coverage for oily or dark skin as it isn’t as translucent as untreated sericite.
Summary for Silicone Treated Sericite Mica
Usage rate:
Up to 100% in powdered products.
Whiteness or opacity:
To make a colour lighter, to cover up imperfections. It won’t make your colours lighter and it’s a medium coverage product, so it will cover up some imperfections in your skin.
Translucency:
The base itself is almost invisible once applied. A translucent product that is virtually invisible when you apply it. Not as translucent as untreated sericite mica.
Skin protection:
Comestic Silicone is approved as a barrier ingredient, so it is going to offer some protection from the elements. The sericite itself does not offer protection.
Slip:
The product feels nice going on and staying on. Offers great slip and glide with a silky feeling upon application and on your skin.
Adhesion: The product remains on your skin. Great adhesion.
Absorbency:
Your colour will remain true throughout the day and not morph into something due to environmental stresses or skin oils. Excellent absorbency and excellent colour retention for people with normal, oily, or darker skin.
Light scattering properties:
To give your skin a dewy glow. Good light scattering properties, but this can make older skin look more wrinkled.
用于焊条中的绢云母粉
由于绢云母黏土的弹性和塑料特性佳，焊条不会那么容易断裂。此外，其如丝绸般和柔滑的特性将延长用于挤压的机器的寿命。它提供更好的光洁度，使外观更佳。
用于橡胶行业的绢云母粉
其中一个主要特性是它将令橡胶产品更为坚固，因此可用来进行加固。炭黑的使用也因此减少。绢云母粉提高产品的尺寸稳定性，比如应力龟裂，以及减慢橡胶老化的现象，加强耐磨的表现，相比之下，橡胶的保存期较短。它拥有极佳的抗酸性和抗碱性，以及具有阻燃和抗腐蚀的特性。
绢云母粉也令橡胶产品的隔热性能提升，减低收缩和变形率。另一个重要特质是绢云母粉可提高橡胶制成品的气体渗透率及产品的伸缩性。
用于涂料的绢云母粉
绢云母粉在涂料行业的用途很广，例如它可用于防腐涂层、抗高温涂层，以及内外墙涂层。该矿物的物理结构提供良好的防水及防火特性，正好适合寻找这些特性的涂料行业。
