Which of the following is used for laminating wood

Options

A. Melamine formaldehyde resin
B. Cis isoprene
C. Urea-formaldehyde
D. Phenol formaldehyde

Answer

To determine which polymer is used for laminating wood, we need to analyze the options provided and understand the properties of each polymer.

### Step-by-Step Solution:

1. **Understanding Lamination**:
- Lamination is the process of bonding two or more layers of material together. In the case of wood, this is often done to enhance its strength and durability.

2. **Identifying the Options**:
- The options given are:
1. Melamine formaldehyde resin
2. Cis isoprene
3. Urea formaldehyde
4. Phenol formaldehyde

3. **Analyzing Each Option**:
- **Melamine Formaldehyde Resin**:
- This is a type of thermosetting plastic used in laminates, but it is primarily used for surface finishes rather than for bonding layers of wood.
- **Cis Isoprene**:
- This is a type of rubber and is not suitable for wood lamination.
- **Urea Formaldehyde**:
- This is an amino plastic resin formed from urea and formaldehyde. It is widely used as an adhesive in wood products due to its strong bonding properties and durability.
- **Phenol Formaldehyde**:
- This is also a thermosetting resin, commonly used in making bakelite and for some wood products, but it is not as commonly used for laminating wood as urea formaldehyde.

4. **Conclusion**:
- Among the options, **Urea Formaldehyde** is the most suitable and commonly used resin for laminating wood due to its strong adhesive properties and ability to form a durable bond.

### Final Answer:
The polymer used for laminating wood is **Urea Formaldehyde**.
