Product Description

RCS 880 Rubber cleaning sheets are used to eliminate pollutants and stains formed on the mold surface. They perform well in a wide range of molds and are able to withstand up to 100t. These sheets offer an good cleaning performance with less smell and fumes.

RCS 880 sheets have good flow characteristics which enable them to clean mold corners and thin gate areas easily. Unlike melamine cleaners, RCS cleaning sheets can even clean the air ventilation areas without causing mold abrasion or corrosion. At the same time there's no need for dummy lead frame or preheating, something that reduces cleaning time and leads to improved production time results and productivity.

RCS 880 Rubber cleaning sheets can remove contamination of molds used in the semiconductor industry for products such as as integrated circuits, diodes, transistors, and LEDs in both physical and chemical mechanisms.

Specific Gravity

Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume.

For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

Shelf Life Shelf Life Shelf life is the amount of time after manufacturing that a product is guaranteed to retain its properties. It differs vastly per product and it is based on temperature and storage conditions. The properties can be guaranteed for the temperature and time range indicated on the TDS since those are the ones tested to be the best for the product.
Shelf Life @ 5°C	240 days

Curing Conditions

Curing Schedule Curing Schedule Curing schedule is the time and temperature required for a mixed material to fully cure. While this applies to materials that cure with heat, there are also other materials that can be cured with UV. Even though some materials can cure on ambient temperatures, others will require elevated temperature conditions to properly cure. There are various curing schedules depending on the material type and application. For heat curing, the most common ones are Snap cure, Low temperature cure, Step cure and Staged cure. Recommended cure type, schedule, time and temperature can always be found on the Technical data sheets.
Cure Time	2-5 min
Mold Temperature	170 °C

Additional Information

Difference between RCS 620 and RCS 880

RCS 880 have higher elastomer content (55%) compared to RCS 620 (40-50%) which makes it more flexible/elastic thus enabling it to reach corners and complex portions of the mold while cleaning.

In addition, RCS 880 has more concentrated cleaning ability since it has no solvent in the composition while RCS620 have additional propylene glycol compound that act as a solvent/plasticiser.

Recommended Application Setting	RCS 620 & 880
Mold Pressure	1600 – 1800 psi or 50 – 120 tons
Mold Temperature	150 – 185 ° degree celcius
Curing Time	150 – 600 seconds
No of Shots	4 to 8 shots

Storage and packaging

These rubber sheets should be kept in room temperature. Their shelf life in these storage conditions is 9months.

They are packaged in PE bags and come in 10Kg (net) boxes. Exact width is not stated since the sheets can be arrayed for the application and width is adjusted to the box size to accommodate the net weight.

Warning

It is recommended to use the sheets in a well ventilated area. Your skin should not come in contact with them when the rubber is hot and you should avoid storing them at temperatures above 30°C.
