Anchor Film-faced Plywood

Introduction

Concrete is an excellent material of construction possessing high strength, stiffness, impact resistance, gain in strength with age, durability, and mouldability. As it has no shape in its plastic stage, it requires to be moulded into various forms using formwork, which consists of the mould in contact with the concrete, the structural supports, and hardware. Among the most commonly used materials for formwork are timber, plywood, and steel plates.

Characteristics of a Good Formwork Panel

Formwork is a temporary means of supporting and protecting fresh concrete during casting and hardening to give the resultant concrete structure a good surface, in the required shape and size. A formwork panel must meet the following functional requirements

Formation of a structure with the desired dimensional accuracy, surface finish, strength and durability.

Protection of the fresh concrete from damages.

Prevention of deformation to the structure from external pressures.

Retention of the fine constituents of the concrete till it hardens.

Ensuring hardening of the concrete without disturbance.

Protection of the concrete from excessive heat and cold.

Re-usability.

Formwork constitutes a major item of cost in building construction. The cost of formwork in turn depends on the performance of the formwork panel in respect of the above requirements. Thus, the sheet material used for formwork has a significant effect on the over-all cost of construction.

Plywood in Concrete Shuttering and Formwork

Plywood is a reconstituted sheet material made from wood. It is made up of several layers of wood, bonded together using a synthetic resin adhesive. The adjacent layers reinforce each other through a cross-laminated construction. Plywood has the following superior features compared to timber panels

High Strength to weight ratio.

High Stiffness to weight ratio.

High surface area to mass ratio.

Excellent finish to concrete.

Re-usability.

When bonded with BWP type phenol formaldehyde synthetic resin, plywood becomes durable against continuous or cyclic exposure to high moisture conditions, and suitable for concrete shuttering work.

Anchor Film-faced Plywood

Anchor Film-faced Plywood is a phenolic impregnated film overlaid plywood plywood engineered to meet the functional requirements of high quality concrete shuttering and formwork. It has the following superior features:
 

Hard and smooth phenolic resin film imparts smooth finish to concrete, and enhances reusability substantially. As a result, there is great economy on account of saving in plastering work and lower consumption of plywood.

Use of selected hardwood veneers imparts high strength and stiffness.

BWP type Phenol bonding makes the plywood withstand several cycles of wetting and drying.

Thanks to these superior features Anchor Film faced Plywood offers to builders and contractors the higher reusability better finish and greater overall economy than plain shuttering plywood.
