Other Polymer Companies

• Polymaster: Australia's most trusted poly tank manufacturer since 1994, manufacturing innovative products for industrial, residential, and agricultural applications.
• Polymer: Pioneer and leading supplier of polyester resin and auxiliaries to the Philippines' Fiberglass Reinforced Plastic (FRP) Industry.

JGSOC

• The largest manufacturer of polyolefins in the Philippines, producing polyethylene and polypropylene resins.
• The first and only integrated PE and PP resin manufacturer in the country.

Petrochemical Production

• Naphtha cracking is a pivotal process in petrochemical production, yielding essential olefins used in manufacturing plastics and other materials.
• Feedstock selection: Naphtha, a mixture of hydrocarbons, is chosen for its high content of paraffin and lower boiling range.
• Thermal cracking: Conducted in a tube-still furnace at temperatures above 800°C.
• Process optimization: Short residence time and high-speed passage through heater tubes prevent the formation of undesirable heavy products and coke.

Stages of Petrochemical Production

• Feedstock (First-generation Petrochemicals): Obtained from crude oil refining and catalytic processes, including hydrocarbon gases, naphtha, benzene, toluene, and xylene.
• Catalytic reforming: Generates a variety of products, including olefins, branched or isoparaffins, and aromatics.

Techniques for Pressureless Processing

• Casting: Used to produce thick-walled articles, embeddings, sheets, and blocks made of polystyrene, polyamides, and polymethylmetacrylate.
• Dipping
• Coating
• Foaming

Bulk Polymerization

• A method that employs only the monomer molecule, an initiator, and a chain transfer agent (if necessary) to obtain the purest form of polymer.
• Can be used for casting objects of various shapes.

Solution Polymerization

• Involves adding an inert solvent to the reacting components, enhancing heat capacity and facilitating heat transfer.
• Reduces reaction rate and molecular weight of compounds compared to Bulk Polymerization.

Suspension Polymerization

• Developed to control the enormous amount of heat release in Bulk Polymerization.
• Involves adding a solvent to the reaction mixture, which is then dispersed in the form of droplets.

Physical Adsorption

• Molecular sieves (zeolites) are widely used to adsorb large amounts of gases.
• Can be regenerated by passing hot dry fuel gas through the bed.

Chemical Absorption (Chemisorption)

• Characterized by a high capability of absorbing large amounts of acid gases.
• Diethanolamine is a favored absorbent due to its lower corrosion rate, smaller amine loss potential, and minimal reclaiming needs.

Water Removal

• Various techniques are employed, including glycol dehydration, solid adsorbents, and others.
