Molding temperature: 200-240℃?
Drying conditions: 80-90℃ 2 hours?
Molding characteristics:
1 , amorphous material, medium fluidity, high moisture absorption, must be fully dried, plastic parts requiring glossy surface must be preheated and dried for a long time at 80-90 degrees, 3 hours.
2. It is advisable to use a high material temperature , high mold temperature, but if the material temperature is too high, it will easily decompose (decomposition temperature is >270 degrees). For high-precision plastic parts, the mold temperature should be 50-60 degrees. For high-gloss, heat-resistant plastic parts, the mold temperature should be 50-60 degrees. Take 60-80 degrees.
3. If you need to solve the water mark, you need to improve the fluidity of the material, adopt high material temperature, high mold temperature, or change the water level.
< p>4. If heat-resistant or flame-retardant materials are formed, plastic decomposition will remain on the mold surface 3-7 days after production, causing the mold surface to become shiny. The mold needs to be cleaned in time, and an exhaust position needs to be added to the mold surface.Extended information:
Features:
1. Good comprehensive performance, high impact strength, chemical stability, and good electrical properties.
2. It has good weldability with 372 organic glass and can be made into two-color plastic parts, and the surface can be chrome-plated and spray-painted.
3. It has high impact resistance, high heat resistance, flame retardancy, and reinforcement , transparent and other levels.
4. The fluidity is slightly worse than HIPS, better than PMMA, PC, etc., and has good flexibility.
Uses: Suitable for making general mechanical parts, reducing wear Wear-resistant parts, transmission parts and telecommunications parts.
According to different needs, you can choose the following adhesives:
1.G-977: One-component room temperature curing soft elastic shock-proof adhesive The mixture is resistant to high and low temperatures, and the bonding speed of different viscosities can be completed in a few seconds to several hours;
2. KD-833 instant adhesive can quickly bond PC in seconds or tens of seconds. Plastic, but the adhesive layer is hard and brittle and cannot withstand immersion in hot water above 60 degrees;
3. QN-505, a two-component adhesive with soft adhesive layer, suitable for large-area bonding or lamination of PC plastics.
4.QN-906: Two-component glue, high temperature resistance;
5.G-988: One-component room temperature vulcanized glue, after curing, it is an elastomer with excellent waterproofing properties , shockproof adhesive, resistant to high and low temperatures. If the thickness is 1-2mm, it will initially solidify in about 10 minutes and basically solidify in 5-6 hours. It has a certain strength. It will take at least 24 hours to fully cure. One-component, no mixing required, just apply after extrusion and let it sit, no need to heat.
