What is it?

As C&W knows it – the milky sap from the Rubber Tree. The raw latex is usually processed to make it 60% rubber, 5% additives and the balance, ammoniated water. The ammonia is added to prevent any decomposition during shipment and storage.

What is it for?

Dipping latex makes a thin film which is then converted to balloons, condoms, medical examination gloves, gardening gloves etc. Latex is also used in paints and adhesives.

In addition to normal 60% Natural Rubber (NR) latex, there is a grade called Prevulcanised (PV) Latex which has been prepared at source with dispersions of cross-linking chemicals. This obviates the need to compound as one would with normal 60% NR latex. This PV Latex issued mainly in “cottage industries” for mould making. The moulds are durable and suitable for producing casts in cold setting resins such as of Plaster of Paris. Examples of products include garden gnomes, statues, and chess set pieces.

How do we get it?

It is imported from Malaysia, Indonesia, or whoever is competitive.

5,000,000,000 (5 billion) – The number of condoms sold each year. Most modern-day condoms (over 90%) are made of NR latex, the rest from polyurethane or lamb intestines.
