Latex powder is extensively made use of in the finishing and developing and building markets. Nevertheless, different sort of latex powder have various attributes and applications, of which VAE latex powder and RDP latex powder are 2 of them. This article will definitely present the differences in between these 2 kinds of latex powder carefully.

1. Active ingredients and Preparation

VAE latex powder is a white or light yellow material with exceptional fluidness, it made from plastic acetate-ethylene copolymer using spray drying. It is risk-free, harmless, eco-friendly. RDP latex powder is a distinct polymer item made from a mix of rubber pieces and polymer bits.

2. Effectiveness features

Adhesion.VAE latex powder has good adhesion and can be tightly bonded to a range of substrates, such as glass fiber, cotton cloth, paper, and so on. RDP latex powder has stronger attachment and can be snugly bound to a range of difficult-to-bond materials such as glass and ceramics.

Environment resistance.VAE latex powder has outstanding weather condition resistance and can keep its initial performance under lasting straight exposure outdoors, while RDP latex powder has a lot more efficient setting resistance and can shield its stable efficiency in serious atmospheres.

Adaptability.VAE latex powder has excellent flexibility and can absorb a particular amount of contortion, making the layer have great result resistance RDP latex powder has higher flexibility and can hold up against higher deformation, making the finishing added strong.

Place on resistance.VAE latex powder has great wear resistance and can stand up to specific rubbing and wear, while RDP latex powder has stronger wear resistance and can stand up to a great deal extra extreme massaging and wear.

Chemical resistance. VAE latex powder has good chemical corrosion resistance and can hold up against corrosion from specific chemicals, while RDP latex powder has much more effective chemical degeneration resistance and can take on rust from far more major chemicals.

3. Application areas

Construction Industry: Both VAE latex powder and RDP latex powder can be utilized in the building and construction market, such as exterior and interior wall surface finishes, water resistant finishes, flooring finishings, and so on. Among them, RDP latex powder can be used in building and construction fields with greater demands, such as highways, bridges, tunnels, and so on

Repaint market: Both VAE latex powder and RDP latex powder can be used in the finishing market, such as water-based coverings, oil-based finishes, powder coverings, and so on. Amongst them, RDP latex powder can be utilized in layers with greater needs, such as automobile coatings, aeronautics layers, and so on

Other fields: In addition to the building industry and the finishing market, VAE latex powder and RDP latex powder can likewise be utilized in other areas, such as the textile market, papermaking industry, packaging industry, etc. Among them, RDP latex powder can be made use of in areas with higher requirements, such as aerospace, medical tools, etc

VAE latex powder and RDP latex powder are 2 different types of latex powder with various characteristics and application fields. When selecting which latex powder to utilize, you require to choose according to the details application scenario and requirements. At the same time, you require to take note of safety and security issues and use approaches throughout use to ensure the effect and safety and security of usage.

Today, business silicon carbide power modules still primarily make use of the packaging innovation of this wire-bonded traditional silicon IGBT component. They face issues such as huge high-frequency parasitic criteria, inadequate warm dissipation ability, low-temperature resistance, and not enough insulation toughness, which limit using silicon carbide semiconductors. The display of superb performance. In order to resolve these problems and fully exploit the huge possible advantages of silicon carbide chips, many new packaging modern technologies and remedies for silicon carbide power modules have arised recently.

Silicon carbide power module bonding approach

Bonding materials have developed from gold wire bonding in 2001 to light weight aluminum wire (tape) bonding in 2006, copper cord bonding in 2011, and Cu Clip bonding in 2016. Low-power devices have actually established from gold wires to copper wires, and the driving pressure is cost reduction; high-power tools have established from aluminum cords (strips) to Cu Clips, and the driving force is to boost product efficiency. The higher the power, the greater the needs.

Cu Clip is copper strip, copper sheet. Clip Bond, or strip bonding, is a packaging procedure that uses a strong copper bridge soldered to solder to attach chips and pins. Compared to standard bonding packaging approaches, Cu Clip modern technology has the complying with benefits:

1. The link between the chip and the pins is made of copper sheets, which, to a specific level, replaces the standard wire bonding approach between the chip and the pins. As a result, a distinct plan resistance value, higher present flow, and much better thermal conductivity can be acquired.

2. The lead pin welding location does not require to be silver-plated, which can completely conserve the expense of silver plating and inadequate silver plating.

3. The product look is totally regular with regular items and is mostly used in web servers, portable computer systems, batteries/drives, graphics cards, electric motors, power materials, and various other fields.

Cu Clip has 2 bonding approaches.

All copper sheet bonding method

Both eviction pad and the Source pad are clip-based. This bonding technique is more costly and complex, but it can attain much better Rdson and far better thermal effects.

( copper strip)

Copper sheet plus cord bonding approach

The resource pad utilizes a Clip technique, and the Gate utilizes a Cord method. This bonding approach is slightly less expensive than the all-copper bonding approach, conserving wafer area (appropriate to very tiny entrance areas). The process is less complex than the all-copper bonding technique and can obtain much better Rdson and better thermal result.
