Sunpine

Pinus caribea hondurensis Morelet Fam. Pinaceae

The tropical pine with the most wider geographical distribution. Good aesthetic appearance, light yellowish coloration,Works easily.

Sunpine Uses

Suitable for construction and carpentry work, it is used to manufacture furniture (beds, windows, wardrobes, chests of drawers, trunks, tables, chairs), floors, sheets for plywood or chipboard, homes, poles, farm poles, crafts, moldings, bodies, agricultural implements, containers, boats, fine brushes and tools handles and to make cellulose pulps.

But it presents problems of nailing and screwing, by frequently mismatching in the joints. Suitable for tongue and groove interior ceilings, provided there are no moisture problems It is usually used for firewood. Sawdust is requested for various uses. It is very important raw material for the production of paper. The resin is in demand in the industry of soaps, disinfectants, turpentine, varnishes, drugs, flavorings, medicines, rubbers and paints
